I think it is a mix of things for him. Arriving at the 11th hour, injuries...then playing in roles that dont suit and in general being in a team that is yet to see continuity due to a huge amount of injuries under a new manager.
In saying that, his control was terrible today and he doesnt seem to have the confidence to step it up and make ahit happen. All that was missing was the high claps.
Back to basics for him...play him deeper...let him get on the ball more and allow him to control the game more.
