Mourinho said that he expects to come up against a very well-organised unit at Stamford Bridge, but believes that his side should have enough to win.
"I am very happy to meet Steve Clarke again," BBC Sport quotes Mourinho as saying. "It will be a difficult game because he organises his teams well.
"Every game Steve Clarke plays I wish he will win, but tomorrow that is not the case which is strange."
Chelsea are currently second in the Premier League.
