Jose Mourinho was happy and looking forward to next week's games.
He said: "The result was hard on Norwich.
They did well and gave us a good first half.
But after the second goal, I was able to rest a few players.
"And then I could start to think about Wednesday and the Champions league match against Porto.
"I think 4-0 is not fair on them.
"Boulahrouz has dislocated his shoulder but Michael Ballack will be fit for Wednesday.
"We are in the quarter final of the cup and now have two more cup finals this week - starting against Porto and the Arsenal on Sunday.
"I don't know if Roman Abramovich was here today, I was doing my job.
"It's his club - he does not have to explain to me - it's his house.
"Thankfully it's the last game on that pitch.
We need a better one when playing the likes of Porto - I told the club two months ago the pitch needed replacing.
"I know all about Porto and have told my players they are a good side.
I will get a reception of two faces.
Thos who understand why I left them to pursue a new challenge will understand and give me a good welcome.
The others who don't know why a proffesi9onal wants to leave won't - but that's football."
Norwich boss Peter Grant was bullish indefeat. He said: "
"We deserved to get something from the game.
"To lose your goalkeeper and have the ball kicked off the line is hard to take.
"But we must take this good form into the league and come back to Chelsea in the Premiership - that's where we should be.
"The pitch was not great, but we won't complain about it.
"It was a leg-sapping match and the players are very tired - as well as they should.
"We put in a great effort but there were bad misses. We lacked that bit of quality in front of goal.
"Chelsea have world-class players, but we were always in the game.
"In general play we were excellent.
"Dion Dublin worked manfully and his experience at the back alongside young players was really needed.
"We went to three at the back in the end, putting Dublin up front, but lost two late goals."
