Brendan Rodgers was proud of his Celtic players despite watching them fall to a 2-1 defeat to Bayern Munich and ultimately ending their Champions League dream.

The best Celtic can do now is progress into the Europa League by finishing third in Group B but the manager was not too downbeat after the result on Tuesday.

He was happy to see them cause Bayern problems, saying his side showed great composure, coordination and quality.

We've broken down the main talking points from matchday four of the tournament.

For all the praise Brendan Rodgers lapped on to his Celtic side he also had to concede some defensive problems were still evident.

It is a problem Celtic know they have to address but unfortunately for them it was all too evident again on Tuesday night.

Bayern's opener on 22 minutes came from a goal kick that found Kingsley Coman.

Dedryck Boyata's poor decision-making mixed with Craig Gordon's hastiness to rush out of his goal cost the home side.

While the shouts that Coman controlled the ball with his hand before finishing were justifiable from the Celtic backline, even without the bad luck it was still a defensive error that cost them again.

The defender can do no wrong just now.

Having just extended his stay at Celtic with a new and improved six-year contract, the boyhood Hoops fan is living the dream.

Tierney is an international regular, fans' favourite with both club and country and can more than hold his own in the Champions League.

He is also still only 20 years old.

His manager also pointed out that he had spent the game coming up against veteran Ajern Robben but did not look a foot out of place. In fact, he called him "outstanding".

The left-back was one of the star men on the pitch against Bayern Munich and if an even bigger force in the Champions League does not snap him up in the near future he is sure to continue being a key player for Celtic on the big stage.

There was no denying Scotland's recent run of form has been largely down to the team spirit shared by the Celtic players who have been dominating the starting line-ups.

It has been a welcome sight seeing the national side bond and gel like a club team while also possessing exiting talent and a strong desire to win.

Those welcome traits were evident again on Tuesday when James Forrest and Callum McGregor combined for Celtic's equaliser.

Forrest had yet another outstanding performance for the Hoops this season while the latter did himself no harm when it comes to cementing a Scotland place under the new regime.

Complete with Tierney, Scott Brown and Stuart Armstrong also putting in strong and sturdy displays, the homegrown talent did themselves proud on the European stage.

Many Celtic fans will feel hard done by not to get at least a point off Bayern and the full-time stats reflect that.

With 50% of possession the sides were hardly split across the pitch. Celtic had 11 attempts to Bayern's nine while both had four on target.

Celtic made 596 passes while their visitors made 641 and both successfully completed roughly the same amount with 83% and 85% respectively.

Mikael Lustig was Celtic's most accurate passer with a 94% completion rate with only Bayern's Corentin Tolisso bettered him with 58 of his 61 balls going to his own teammate.

Scott Sinclair, who was on the pitch for just over an hour, had the lowest number of passes for Celtic.

He attempted just nine but did successfully pull off eight of them.

If you love your permutations and football arithmetic you will not be enthralled by the Group B table.

Match day four's results have left it quite straightforward as Paris Saint-Germain lead on 12 points from 12 after beating Anderlecht 5-0 on Tuesday night.

It was not their first comprehensive victory of the group stages either, with them also beating Celtic by the same scoreline in the opening game of the tournament.

Having also won 3-0 and 4-0 in their other respective matches it takes their aggregate score to a whopping 17-0 with two games remaining, the best a side has performed in the Champions League after four games.

No other side even comes close in terms of form. Manchester United have also won four out of four but have scored significantly less goals.

The same can be said for those with a 100% record playing on Wednesday night.

Manchester City and Besiktas are also looking for their fourth win but their goal difference does not come remotely close to PSG's.

It s difficult to see who can stop them in their tracks which begs the question, are the Group B teams getting an early glimpse of the tournament winner?

There was a glimmer of hope when Celtic equalised that they were on track for another momentous home result in the Champions League against European giants.

It was not to be and ultimately it stretched their run without a win over a German side at Celtic Park to 14 and a half years.

The last time Celtic enjoyed a victory on their own patch against one of Deutschland's finest was during the 2002/03 run to the UEFA Cup final, beating Stuttgart 3-1 in the fourth round first leg.

Celtic have since drawn 0-0 with Bayern Munich, lost 1-0 to Hamburg and more recently 2-0 to Borussia Monchengladbach in last year's competition.
