Wenger rails at referee as City surges further ahead

MANCHESTER, England - Arsene Wenger accepted leader Manchester City would be "hard to stop" in its quest for the Premier League title - especially if it continued to get preferential treatment from referees.

The Gunners manager accused City forward Raheem Sterling of diving after he won a penalty in his team's 3-1 victory over Arsenal at Etihad Stadium on Sunday.

Wenger was furious with the performance of referee Michael Oliver, who awarded the spot-kick and a dubious goal, which the Arsenal boss claimed was offside.
