Joey Barton's Rangers future remains in serious doubt following a series of controversies with the midfielder currently serving a three-week suspension.

In just five months in Glasgow, the controversial Englishman has rarely been out of the headlines due to his bold claims, on-field performances and the publication of his autobiography.

Here's a timeline of his time in Scotland so far.

In the week leading up to the Scottish Cup final, the Burnley midfielder arrived in Glasgow to hold talks with Mark Warburton and David Weir.

Barton expressed his desire to put down roots somewhere as he considered an offer to remain at Turf Moor.

After losing out to Hibernian at Hampden, Mark Warburton started preparing for life in the Scottish Premiership by signing Barton on a two-year contract.

The 33-year-old thanked the Clarets for their support as he described the decision to leave as the "toughest decision of my professional life."

He said the "competitive animal" in him couldn't resist the chance to join the Ibrox side.

"I came up here a week ago and I was just blown away by the history and tradition in the stadium.

"That is really seductive for someone like myself, who is a football man.

"I had a great tour guide in [assistant boss] Davie Weir. As soon as I walked into the trophy room and saw the portrait of Bill Struth and the 54 pennants on the wall I was just bitten."

The Englishman also played down claims he was a childhood Celtic fan, insisting the only club he really cared for was Everton.

Speaking in his one and only media conference as a Rangers player, Barton addressed his bad boy reputation and insisted he was a changed man.

On his reputation, he said: "I know who I am. The man I am. I know what I bring to a team and an organisation when I'm in there.

"There's been obviously times in the past when that hasn't always been the case, and I haven't always been on my best behaviour.

"But that's in the past. All I can do is be the man I am today, and affect things in that respect.

"I'm aware of the contribution I can have within an organisation. The main thing is for me to come into work every day, look my team mates and the people I work for in the eye and [letting] them know you're doing everything you can to make it a better place."

On the day Euro 2016 kicked off, Barton launched his first verbal volley towards Celtic and their captain.

He said: "People keep talking about Joey Barton v Scott Brown. He ain't in my league.

"He's nowhere near the level I am as a player. He can't get to me. If I play well, Scott Brown doesn't stand a chance.

"That's not me being blasé. That's me stating what I believe."

Barton's criminal record as well as media commitments during Euro 2016, meant he didn't take part in Rangers' pre-season training camp in South Carolina.

Warburton's men played one friendly during their time in the States before returning home to prepare for the start of the League Cup.

Scott Brown laughed off Barton's claim from earlier in the month and said he would get on fine with the "Celtic fan".

The midfielder joked "I'm not in his league. He's in my league."

It wouldn't be the first time the Celtic skipper got one over Barton.

Having missed the League Cup opener against Motherwell with his fitness not yet up to scratch, the Rangers fans finally got their first glimpse of Barton as a second-half substitute against League 2 side Annan.

Barton replaced Josh Windass on the hour mark and received warm applause from the Ibrox crowd.

After much anticipation, Rangers are held at home to Hamilton on the opening day of the season with Barton chosen as man of the match.

Ali Crawford's nutmeg on Barton in the first half of the game went viral online with the midfielder insisting he wasn't surprised by the standard of Scotland's top flight.

He told Sky: "We knew every team coming to Ibrox was going to be like a cup final. For a lot of teams it is like a cup final and we've got to be ready to meet that and match that."

Rangers secured their first league win of the season with a 2-1 triumph at Dens Park but many were left unimpressed with Warburton's midfield shape in the second half of the game.

Barton was partly at fault for Mark O'Hara's goal from a corner, failing to track his marker and allowing the former Kilmarnock man to head home.

Warburton stuck with the midfield trio of Barton, Rossiter and Halliday for the home match with Motherwell with a last-gasp Kenny Miller striker giving the hosts a 2-1 victory.

Not content with picking a verbal battle with the captain of the Scottish champions, Barton turned his attention to their manager Brendan Rodgers. During an interview with TalkSport, he claimed the Northern Irishman was going through a mid-life crisis and made derogatory remarks over Rodgers' personal appearance.

Rodgers declined to respond to Barton's jibes.

Rangers' sluggish start to the domestic season continued with a 1-1 draw at Kilmarnock with Barton on the end of a reckless tackle from Greg Taylor.

The incident couldn't hide another poor display from the experienced midfielder, who was passive as Killie got on top of the Light Blues in the middle of the park for the opening 45 minutes.

Barton was poor on the ball and was cautioned before being replaced by Andy Halliday after 69 minutes.

After much hype in the build up to the match, the anticipated battle between Barton and Brown was a non contest with Celtic dominating the middle of the park as Rangers' older heads toiled.

In the middle of the park, Barton and Niko Kranjcar couldn't live with Celtic's attacking quartet of Dembele, Rogic, Sinclair and Forrest with Brown describing the contest as "men against boys".

Philippe Senderos' red card saw Barton fill in at centre back later in the game but he was unable to stop Dembele completing his hat-trick.

The day after the game, Barton took to Twitter to give his verdict on his own display and that of his team-mates.

As the fall out from the Old Firm derby defeat continued, Rangers players had their say on what exactly had gone wrong against Brendan Rodgers' side.

The result was a frank exchange of views between fellow midfielders Barton and Halliday with the Englishman called to Warburton's office to discuss what had been said.

With Barton refusing to back down, the Rangers boss banished the player from training for the remainder of the week and told him to consider his actions.

Ahead of Rangers' regular news conference to preview the weekend's clash with Ross County, photographers at training noticed Barton's absence.

Having been told the player was not injured, news of Barton's expulsion earlier in the week soon filtered through.

Later that evening, Barton took to Twitter to present his side of the story.

Anyone expecting Barton to keep quiet after his statement on social media the previous night would be mistaken with the 34-year-old calling TalkSport to discuss the disagreement in full.

During his chat with Jim White, Barton called Mark Warburton's handling of the affair "strange" before insisting he had not hing to apologise for.

On his relationship with Halliday, he added: "There is absolutely no issue with me and Andy. We sat down in the dressing room afterwards and spoke through what was said.

"Andy is a mad, passionate Rangers fan, he's stood in the terraces, so I've got great respect for him. He cares deeply about making the club better, as I do."

Following the 0-0 home draw with Ross County, Barton's absence remained the main talking point but the Rangers manager was refusing to talk about the missing man.

Describing the circus as "an internal matter", Warburton left his media conference early after repeated questions surrounding the player's future.

Barton, Warburton and members of the board met at Ibrox to discuss whether the player would remain in Govan.

The club imposed a three-week suspension claiming "time and space is required for both the club and the player to assess all that has happened."

Upon leaving the stadium Barton was asked if was still a Rangers player. "I think so" was the reply.

With his autobiography set to be released later this week, Barton sat down with several English newspaper reporters for feature length interviews to preview his book, entitled "No Nonsense".

During his chat with The Guardian's Donald McRae, Barton discusses his row with Rangers, the claims he has made during his time in Scotland and reflects on his decision to join the Ibrox side.

"Knowing what I know now?" he said.

"Reflecting on it, would I have made the same decision? Probably not. I've even been honest with people about that. There is an honesty that I am operating which means some people think I'm critiquing them. But I know that in time it will turn out to be the right decision. As tough as it is, adversity brings out the best in you."

Barton also gives his view on the state of Scottish football and his team-mates, saying: "It's difficult when I'm playing at a level which, clearly, I've not played at before.

"It's a much lower level and I'm trying to help people get to a higher level. They think me helping is me trying to say: 'You're not good enough.' It's difficult."

If he didn't have enough on his plate then Barton discovered he is being investigated by the Scottish FA for breaching their rules on gambling after allegedly betting on Celtic's Champions League defeat to Barcelona.

The governing body's compliance officer along with the Gambling Commission is looking into claims the Englishman placed money on Celtic's heavy defeat at Camp Nou last Tuesday after a red flag was raised.

Another section in Barton's book centres on claims that Celtic were keen to sign the player from under Rangers' noses at the last minute.

The Liverpool-born player said he was never going to change his mind and "let down Rangers."

This prompted a response from Celtic chief executive Peter Lawwell, who gave a different version of events.

Lawwell said: "An agent called me saying that Joey was going to sign for Rangers but he would really prefer to come to Celtic and were we interested in signing him, but it wasn't something we wanted to pursue.

"These things happen to players sometimes in football, but needless to say we wish Joey well at his new club."

After being investigated by the SFA, Barton is eventually issued a charge with breaching the gambling rules.

It's not only the game between Barcelona and Celtic though, he allegedly bet on 44 football matches in total since his arrival in Scotland.

His hearing was set for October 27 but was later rescheduled for November 17.

Barton was due to return to the club on October 10 but Rangers extended his suspension by another week.

A statement on the Rangers website read "This is part of a formal disciplinary procedure and Joey has been instructed not to return to Ibrox or Auchenhowie until further notice."

Mark Warburton's pre-match media conference was cut short after PR man Jim Traynor stepped in to stop questions about Barton.

He was talking to the media ahead of their trip to Inverness when he was grilled on the club's decision to extend Barton's initial three-week ban.

Proceedings were brought to a halt after he continued to be pressed on the matter, despite stating he would make no comment on the matter. He later returned to answer questions on other topics.
