However, asked what will happen if Chelsea fail to win in the final, the Italian said: "This is a difficult answer but I think if Grant doesn't win, I think he's finished in the job.
"I think if Grant wins something, then okay, maybe he'll continue, but if not... I don't know the mind of Roman Abramovich, it's very difficult to know what he thinks.
"It is the first (European Cup) final of Chelsea's history, going to Moscow, it's fantastic for him. He'll be very, very proud.
"It's a great achievement for English football."
