5 Players who came back to haunt their former clubs

2. Mo Johnstone RANGERS vs Celtic

Maurice John Giblin "Mo" Johnston is in the history books more for his religion than his football. Only the second player to have played for both Celtic and Rangers since World War II, his move to Rangers in 1989 also made him the highest profile Catholic to turn out in Glasgewian blue. Hated passionately by both sets of fans – the old nes for ‘kniving them in the back’ and the new onse for his denomination – he did however come back to Parkhead to rub their noses in.

Already trailing by a margin to Rangers in the Premiership, the first ‘Old Firm’ since Johnstone’s move was a matter of great prestige for the men clad in green and white. Except Johnstone chose this particular movement to endear himself to the Rangers faithful. Latching onto a hashed clearance just outside the box, he set himself with a lovely touch before hammering a shot low into the corner of the goal. Everyone clad in blue exploded, and they fell in love with him – almost as much for his wild celebration as for the lone goal in the game. He had just won them the bragging rights in one of the greatest grudge derbies on the planet.
