Depay is an easy scapegoat for blind, he may not have played well recently but who has in that team and blind hasn't been great as a manager either
Depay clearly has talent he also some issues and work to do but given he is young, adjusting to a new league and trying to fit into an attack which hardly functions at times I am not surprised he is finding it tough. it seems very early to be writing him off and the criticism he receives in the media isn't entirely justified at times.
I think he could be a special player in the right set up, if we can get a right winger who can actually go on the outside of a full back and play martial through the middle I can see depay being much better. Martial drifting out wide and depay cutting in from the left is potentially very exciting. Until we start finding players that compliment each other and building those kind of patterns in attack I think most of out attacking players are going to struggle.
