Manchester City opened up a three-point lead at the top of the Premier League with 3-0 win over Fulham on Saturday as Arsenal returned to form with a 7-1 thrashing of Blackburn.
City, who suffered a surprise defeat at Everton in midweek, bounced back with a straightforward victory over the Cottagers at a blizzard-hit Eastlands.
Sergio Aguero set City on the road to three points with a first half penalty before Roberto Mancini’s side eased into a 2-0 lead with a Chris Baird own goal. Edin Dzeko added a third on 72 minutes.

Disgruntled Arsenal fans had reportedly been planning protests at the Emirates after Arsene Wenger’s side had slid to three consecutive league defeats and a disappointing draw at Bolton in midweek.
Van Persie took his tally for the season to 28 after striking in the 2nd, 38th and 62nd minutes, with Alex Oxlade-Chamberlain (2) and Mikel Arteta getting the other goals before substitute Thierry Henry completed the scoring.
Morten Gamst Pedersen was the lone scorer for Blackburn, who also had Gael Givet sent off for a wild challenge on van Persie just before half time.
Wenger meanwhile praised the contribution of teenage winger Oxlade-Chamberlain.
“Alex was not ready earlier in the season but he has made a big step in the last months, he produces team play and is not only going forward but contributes to the build up and defending,” Wenger said.
“He has improved very quickly and he is a fighter as well in his personality. He plays like a guy who had talent in September but is much more mature now.”
Rovers’ beleaguered boss Steve Kean was left bemoaning Givet’s dismissal.
“It was a tough afternoon,” Kean said. “When you try to compete with 11 men it’s hard enough. The biggest bearing was the early goal and the sending off and the referee did not have a tough deciison to make.”
