Martinelli on thin ice?
We get the sense that Gabby isn't exactly in Arteta's good graces as it is, and his offside call after delivering what should have been the game-winner will irk Arteta to no end.
In truth, there was little, if any reason for Martinelli to be offside at that stage of the Gunners' build-up and often we see games decided by small margins and this was another example.
If Martinelli remains onside, there's a great chance Arsenal will win this game and close the gap on league leaders Liverpool to just four points. But alas, that's not the case.
Martinelli is struggling for form, and mental errors like this won't help his case for more minutes.
