While Sulley Muntari scored the winner from the penalty spot against hot favourites Manchester United with 13 minutes to go, Distin found himself in the eye of a storm.
The United winger felt he should have been awarded a penalty in the sixth minute when he danced into the area only for Distin to block his path.
Distin is adamant his challenge was fair.
"If every time you touch a player it is a penalty, how do you defend?" said the former Manchester City centre-half.
"This is football - it is a contact sport.
"I went shoulder to shoulder with him. I was not going to move out of the way.
"If you cannot do this and you cannot do that, then you are not able to defend."
