Mourinho said: "I had been thinking of playing in a particular way.
"But now I have to think about it all over again from scratch because I have four players who won't play.
"We're in the same situation we found ourselves in at the start of the season - only then we were playing friendlies and now we're facing the world champions.
"I now have to think of how to play the game without my four central defenders.
"But, at Inter, when we find ourselves in difficulties, we have always found a solution to win the game."
