Ally McCoist insists he could tell that all was not well in the Rangers camp prior to their run of two draws and a defeat earlier this month.

Philippe Clement's march toward the top of the Premiership table badly stalled as Rangers managed just a point in each of their games against Celtic and Dundee, with Ross County managing to inflict defeat on the Ibrox club in between.

Their faltering form has been badly timed, with Celtic now holding all the aces in the title race. 

There are only three points in it, but the Hoops do boast home advantage for the fourth and final installment of the Old Firm derby on Saturday, May 11.

McCoist, who hasn't yet given up hope that his former side can achieve the league title, pointed out that there were wearing signs of a collapse from his old club.

"The signs were there and I'll tell you why," explains McCoist to "They lost to Motherwell at home (first game in March) and their performance was very poor.

"But they got away with that because Celtic lost at Hearts in the same round so that was kind of glossed over.

"I could tell that all wasn't well in their camp, but to be honest, I couldn't see a collapse of that size coming. With the draw against Celtic, they've only taken five points out of a possible 15.

"I really don't think it's finished. The one thing that will have to happen, I think, is that Rangers will have to go to Celtic and win. But looking at the other teams, a side like Kilmarnock is doing really, really well and both Rangers and Celtic have dropped points already against them.

"Derek McInnes has done a fantastic job there, and obviously there is Hearts as well, so I think there will be one or two twists and turns."
