Rangers boss Walter Smith admits the Old Firm tension has driven him to retirement. After almost 80 games against Celtic, the Rangers gaffer revealed he has had his fill of them now.

Smith said: "I will not miss the Old Firm games. Definitely not. They have never been that pleasant. You are just relieved to get them over and done with. The winning is a relief and losing is a torture."

The veteran gaffer, who retires at the end of the season, added: "When you reach a certain number of games you say to yourself 'it's time to go'.

"I always think I can get motivated, but all the stuff that surrounds the Old Firm game makes it harder for you to do that.

"In all truth I will not miss that aspect of it.

"It has nothing to do with results.

"Everything that surrounds it starts to be a problem when it used to be a challenge."
