Manchester City boss Roberto Mancini was delighted with Pablo Zabaleta's performance at left-back for their win over Arsenal.

The Argie hit the post late on in the 1-0 triumph.

"In a top team there are 11 players," said the Italian.

"But if we want to win and improve, we need to have 20 good players that have a good attitude.

"Pablo is a very clever player.

"He knew before the game it would be difficult. I told him if he played very well against Theo Walcott we would probably win the game."
