Pellegrini: Costa needs to change

Manchester City manager Manuel Pellegrini believes Chelsea striker Diego Costa should change his game in the light of the Liverpool stamping controversy.

Costa has been banned for three matches - ruling him out of Saturday's top-of-the-table Barclays Premier League clash with City - after being found guilty of violent conduct over a clash with Liverpool's Emre Can.
Pellegrini was asked his opinion on the matter at a press conference to preview the game at Stamford Bridge.
The Chilean said: "He is a great player, a very important player.
"He has his character, it is not an easy character, but I hope for him that (with) this punishment - and I am not trying to take advantage for the game tomorrow - it will be a good thing for him to change in the future because he doesn't need to do it in that way because he is a very good player, a top player."
Pellegrini's remarks were unlikely to receive an immediate response from Jose Mourinho as his Chelsea counterpart did not hold his regular press conference on the eve of the match.
Other than that, however, Pellegrini was unwilling to comment on many matters specific to Chelsea for fear of stoking his perceived rivalry with Mourinho.
"I don't talk about Mourinho," he said.
