He had a stormer. Should have had 2 assists too if Martinelli scored that early one he put wide and if Ode had taken that shot. Other than that he was just generally great, his pressing and dribbling were top class, as was his link play.
Arteta needs to be careful with him though, and the rest of the front 4. The pressing he wants is intense and the players looked fucked after an hour. He has to get better with his substitutions or we'll end up with a load of injuries ruining our season again. Its also a big reason why we lose control of games in the second half.
