The Hoops legend believes he could be heading back to England.
Former Celtic striker Chris Sutton has told the Daily Record that Rangers coach Mark Warburton does not feel like he belongs in Scottish football and believes a return to England could be on the cards next season.
London-born Warburton looks set to win promotion back into Scotland's top flight this term as the Glasgow giants boast an unassailable 12-point lead at the summit of the Championship.
Should they achieve promotion, it would be Rangers' first season back in the Premiership following a financial meltdown in 2012 which saw them demoted to the fourth tier of Scottish football.
This is the ex-Brentford manager's first season in Scotland after leaving Griffin Park at the end of last season.
But it is set to get much tougher for Warburton, whose troops face Celtic in a Scottish Cup semi-final next month, and Sutton believes that a bad result at Hampden, coupled with a lack of financial backing in the summer, could see him return to England - especially if their return to the big time goes pear-shaped.
"Put it this way he’s going to be under a pressure he has never experienced at Rangers [if they struggle to compete with Celtic and Aberdeen next season]," Sutton wrote in his column for the Daily Record.
"What has gone before will be like a tea party and he’ll have to evaluate whether he’s willing to suffer, especially if offers come from down south at the same time.
"Warburton will not be in for the long haul at Rangers but with a trouncing by Celtic and not enough investment in the summer, a smart guy will hedge his bets and head south, where I think he feels he belongs."
