Ryan Giggs has admitted games like the Manchester derby are the reason why he is still operating at the highest level.
Should he play some part for Manchester United at the Etihad Stadium, it will be Giggs' 908th appearance for the Red Devils, an incredible 36 of which would have been against City.
"These are the sort games which I am still involved in football for," he said. "They are big, title-deciding games. Apart from cup finals this is as big as you can get."
