Kezman told the Daily Mail: "Under Mourinho, Chelsea were a machine - and they worked for 90 or 95 minutes without mistake or faults.

"If Mourinho had been in charge of this match, of course it would have been different.

"He's a very different coach, and in his time there were no surprises and no mistakes. Everything worked fantastically. They don't have the same spirit in the team any more.

"We are full of confidence for the second leg. We will not show as much respect for them in London."
