Manchester City boss Roberto Mancini hopes not to be haunted by past players against Aston Villa.
City could come up against three of their former players at Villa Park in Richard Dunne, Stephen Ireland and Shay Given, the last two of whom Mancini sold.
Mancini, however, does not believe the trio's past will be a big factor in the game.
He said: "We are not playing Manchester City against Ireland, Given and Dunne - it is Aston Villa against Manchester City.
"Aston Villa are a good team, they have good players and if we want to win in Birmingham we must play a very good game.
"The other things are not important. Shay and Ireland are playing in a good team."
