Ally McCoist believes Rangers will find it incredibly tough to beat Celtic this weekend
Rangers have lost all three matches against Celtic this season with Brendan Rodgers' side taking the Scottish Premiership by storm.
They already have one trophy and the title is all but sewn up leaving the Scottish Cup match this weekend with even more importance.
Rangers will be desperate to prevent their arch-rivals from winning the treble.
But McCoist reluctantly admits it will be a tall order for caretaker boss Graeme Murty to cause an upset in the Scottish Cup.
