He's barely been played wide though, although I understand he's barely played at all since joining on the whole.
From this season I can remember the first half against Everton (a) where he was on the right and struggled with Baines/Pienaar and then Man Utd (a) where he played advanced on the left and was very good. After a bit of digging there were also the two earliest Europa games and Maritimo where he scored. The rest of the time has been bits and pieces here and there, including last season (where he impressed out on the right in cameos and managed to get into the team).
Not exactly much to go on. Yesterday we had lost our foothold even before Gouffran's injury, too, it was a tough situation to come into.
