#4. Kenny Miller

****

One of the few players to cross the Old Firm divide, Kenny Miller has now completed four seasons in his second spell at Rangers.

A player with a knack to turn up in big games, Miller has scored 32 times in 99 appearances during his second spell. An impact player off the bench, Miller is a dangerous player in the box with a wicked shot on him.

Provided Rangers keep the Celtic forward line at bay for a majority of the game, the outside right forward, Miller an experienced old head can come off the bench and make an impact.
