"I don't have to prove anything to anyone. The Chelsea fans respected the way I played football. They saw that I am a fighter and it will be tough for me to see them again and play against them.
"I am wondering how our fans will react because when we beat Sevilla there were 100,000 people in Istanbul, but Chelsea will be even bigger."
Kezman feels his side will have the upper hand now that Avram Grant and not Jose Mourinho, the man who signed him for Chelsea, is in the opposing dug-out.
The Serbian international claims Grant has ruined the team spirit that the Portuguese built and added: "When Mourinho was there, Chelsea was like a machine. Everything ran like clockwork. Now, talking to old friends at the club, I understand it's not so good.
"There are rows on the training pitch, the kind of problems that never would have happened when Mourinho was in charge."
