Former Celtic striker Chris Sutton believes arch-rivals Rangers have more chance of winning the Scottish Premiership this season than the Parkhead club.
That is despite Danny Rohl's men falling four points behind leaders Hearts - and being displaced by Celtic in second place - after Motherwell's weekend win at Ibrox.
While some bookmakers now have Martin O'Neill's charges as favourites to defend their crown, Sutton - who won the domestic treble and reached the 2003 Uefa Cup final under O'Neill - doesn't believe his old side will come out on top.
When asked on BBC Radio 5 Live's Monday Night Club whether he thought Rangers have more of chance than Celtic of emerging victorious from the fascinating three-way battle for the title with Hearts, Sutton was unequivocal.
"Yes," he said. "Bearing in mind Celtic haven't beaten them [in the league] and they've got to go to Celtic Park and it wouldn't be a great surprise [if Rangers won]. Celtic are finding a way but I do not think that's sustainable.
"I watch Celtic every week. Even on Saturday night against Falkirk, they just aren't convincing.
"At this moment in time under Martin O'Neill they are finding a way but I don't believe, and I've maintained this for a while, that Celtic can win these remaining four games. I really don't believe it.
"I'm not sure Celtic will go to Hibs and get a result. They won there earlier this season but Hibs beat them at Parkhead and drew at Parkhead. Celtic haven't beaten Hearts and Rangers [in the league] all season."
