Mourinho said: “The result was a bit heavy for Norwich. They played well and gave us a difficult first half. To be fair I think we were a bit lucky to be winning 1-0 at half-time.
“In the second half, the second goal gave them no chance to react. After that we had a lot of chances and space and I could rest players and start thinking about the game on Wednesday.
“I thought before the game I could give some rest to some players so I left Ricardo Carvalho and Claude Makelele out and put some players on the bench.
“The first moment I thought the game was over, I took off Didier Drogba and Frank Lampard.”
