Manchester City boss Manuel Pellegrini was left frustrated with their 1-1 draw at Everton.

The Chilean blamed missing a number of first-half chances for the two dropped points at Goodison Park after Steven Naismith's header cancelled out Fernandinho's 74th-minute goal.

Pellegrini feels things will turn with the return of Sergio Aguero.

"It is important for the team. Sergio just worked two or three days with the squad this week, and now he has a full week to continue working," said Pellegrini, who refused to discuss the controversy around Frank Lampard's contractual issues.

"I think we really dominated the game, especially in the first half, and we had clear chances but we didn't score.

"Really we must make a difference in the first 45 minutes when we played very well. We created a lot of chances but we finished in the wrong way.

"It (Aguero's return) is important for the team. Sergio worked for just two or three days with the squad but now he has a full week to continue working.

"I hope he will return in a few days and perform how he did before he was injured."
