Chelsea boss Jose Mourinho refused to discuss Roberto di Matteo's influence at Stamford Bridge yesterday.
Unlike Mourinho, the Schalke coach has managed to lead Chelsea to Champions League glory.
"Don't ask me to speak about him," said Mourinho. "The history is the history that he was on Chelsea bench when Chelsea won the Champions League. He is a historic name in this club. I have nothing more to say.
"My name is in the history of this club. A football club is made of many, many names not one or two names or one player or one manager.
"I did my history here and now I have the chance to make more history here and he was Chelsea manager and he did his history here. I won it twice. For Chelsea, zero."
