West Brom 2-1 Arsenal: Arteta own goal sinks Gunners

Mikel Arteta's own goal consigned Arsenal to a 2-1 defeat against West Brom that gives Manchester City the chance to take sole ownership of top spot in the Premier League.

Santi Cazorla had a major chance to salvage a draw and spare his compatriot's blushes six minutes from time from the penalty spot, but he slipped as he took the kick and skied his effort over the crossbar.

Arteta put the ball into his own net after replacing the injured Francis Coquelin in the 14th minute before he was then forced off himself with what appeared to be a calf problem early in the second half.

Arsenal dominated the early proceedings and deservedly took the lead through Olivier Giroud. 

But West Brom responded well to going behind and James Morrison found the net from Chris Brunt's free kick.

Arteta then deflected a cross from the left past Petr Cech to gift West Brom the lead and Arsenal saw their best chance of a draw go to waste when Cazorla's slip ended their chances of extending their six-match unbeaten run.
