Manchester City defender Vincent Kompany has stoked up the mind games between the two Manchester clubs by claiming he is "happy" that Wayne Rooney is on form.
Despite his lack of game time during pre-season, Rooney has made a blistering start to the campaign, including two goals in Tuesday night's Champions League win over Bayer Leverkusen at Old Trafford.
And the Belgian international might have raised a few eyebrows when he said: "It's brilliant he's doing well again.
"You want to play against top players at their best. That's personally how I feel about it.
"I always want to play against payers when they are at their best. I'm really happy for Wayne that he's on top form."
Kompany, who returned to the City starting line-up during their win in the Czech Republic on Tuesday, also believes David Moyes' previous record against his team - which stands at 10 wins from his last 14 matches against the Blues - won't have a bearing on the outcome of Sunday's match.
"It’s a different team, it’s a different season and I would say there has never been anything too predictable in the derby," he said.
"Nobody predicted we would win 6-1 at Old Trafford, that they would beat us at the Etihad and that we would win at Old Trafford.
"The derby is always a game you look forward to. And I don't think it's just the people in Manchester, but all over the world who look forward to enjoying it. It's a game that attracts a lot of attention."
The first Manchester derby of the season is set to be a classic, with both sides eager to strike the first blow in what is sure to be an exciting Premier League season.
