Manchester United goalkeeper Ben Foster insists they're not bothered by what derby rivals Manchester City have been doing this season.
The Blues have made an impressive start to the campaign, leading many to predict that they will break the league's long-established top four, and challenge for the title.
But Foster said: "We don't talk about them in the dressing room. It's not something that comes up. We just concentrate on our own football.
"We've got some of the best players in the world in our dressing room. We are not thinking about City."
The United goalkeeper endured a deafening night in Besiktas's Inonu Stadium in Istanbul on Tuesday. But he knows that the atmosphere will also be incredibly intense and passionate at Old Trafford.
He said: "Some of the lads have played in dozens of these derbies, and they reckon that everybody seems to step up their game by 10 or 20 per cent."
