Manchester City midfielder David Silva is confident they can end Diego Costa's goalscoring run for Chelsea tomorrow.
The two title favourites clash at the Etihad on Sunday when City playmaker Silva will come up against his Spain teammates Costa and Cesc Fabregas.
"Diego has made a huge impact," he said. "It is not easy to adapt but he has clearly done it very quickly.
"He's scored seven times so far so that record speaks for itself. That's very important for Chelsea but not that good for us. But we've got a good defence and I believe we can stop him on Sunday.
"I have a very good relationship with both players. I think Chelsea have made some fantastic signings this summer but our friendship will be set aside because we are going out to win.
"I've known Cesc since we were 16-years-old and were in the Spanish youth squads together.
"I'm looking forward to facing him but in pretty much every game now I seem to be up against a Spanish teammate - when we play Arsenal it's Santi (Cazorla) or when it's United it will be Juan Mata.
"But it's really all about how the team plays, and our aim as always is to go out and win the game."
