Manuel Pellegrini: "It was very important for the team to continue in the Capital One Cup.
"We knew it was not going to be an easy game because Leicester are a very good team, they were playing at home and were motivated.
"The team played very well, especially in the first half. Maybe when the score was 3-0 we stopped a little bit in our pace.
"Leicester had possession of the ball in the last minutes but I think it was a professional performance in all senses.
"Pablo (Zabaleta) has a problem with his hamstring. We will see tomorrow how serious it is. It is the only bad thing of this game.
"Of course now we don't have a (right) full-back. Maybe we will have to see what we can do in that position.
"I have always said Edin Dzeko is a very important player.
"He hasn't been playing normally in the 11 starting because (Alvaro) Negredo and Aguero are playing well, but every time he has played he has played very well."
