Confident Frank McAvennie reckons a timely Kyogo Furuhashi injury return would shake Rangers ahead of their Celtic showdown.
The striker has been out since sustaining a hamstring injury at St Johnstone on Boxing Day but could be in line for a return for derby day having been spotted in Lennoxtown training.
Kyogo has stated his is nearing full fitness but it remains to be seen if Ange Postecoglou will throw the striker in for the top of the table Premiership clash.
