Skipper Robin van Persie scored a hat-trick as Arsenal beat Chelsea 5-3 in a remarkable Premier League match at Stamford Bridge but Manchester City stayed top of the Premier League with a 3-1 home win over Wolverhampton Wanderers on Saturday.
City stayed five points clear at the top from Manchester United and moved nine clear of third-placed Chelsea with second-half goals from Edin Dzeko, Aleksandar Kolarov and Adam Johnson.
Wolves' goal came from a Stephen Hunt penalty after City skipper Vincent Kompany was sent off.

Those results left City top with 28 points from 10 games, followed by United (23), Chelsea (19) and Newcastle United (19) until they meet Stoke City on Monday.
