Manchester City boss Roberto Mancini admits he's frustrated by having an inconsistent line-up since his arrival.

Carlos Tevez is set to play at Chelsea after spending two weeks in Argentina at the bedside of his baby daughter, who was born prematurely.

Yet the South American will not be able to team up with Emmanuel Adebayor, who is now suspended for City's next four games following his dismissal in Wednesday's FA Cup exit at Stoke.

"In the last two months I have had a lot of problems," said Mancini. "I have never had all the players.

"Carlos had to go home, and Emmanuel has been playing very well but now he can't play for four games.

"If we had Emmanuel and Carlos together, the results would have been different."
