Mark Warburton has hit back at Chris Sutton's claim that the Rangers job is "too big for him", taking a thinly-veiled swipe at the Englishman's views.

Former Celtic striker Sutton had criticised the Ibrox boss' handling of the Joey Barton row after the midfielder was involved in a training ground bust-up with team-mate Andy Halliday and Warburton himself.

Asked for his reaction to Sutton's comments, the Rangers boss said: "I only value the opinion of people for whom I have one iota of respect. Take from that what you will."

Speaking on BT Sport ahead of Sunday's game between Inverness CT and Celtic, Sutton said: "Bad management on the pitch, bad management off it.

"They've just had their pants pulled down by their biggest rivals and he's coming out moaning about negativity?

"The job's too big for him in my view. This isn't Brentford. This isn't the City. And he's coming out with 'it's the best performance of the season?' Do me a favour."

On Monday, Rangers announced midfielder Barton was suspended for three weeks.
