His lack of form is not down to having no Poveda and no Roehl. Röhl was here last season as were Musaba, Windass and an on fire Gassama. he failed to score in the league last season, as he has done so far this season.
I don't know what the problem is but it is not the lack of Poveda or Roehl or of solid professionals around him. We were around the play offs for most of last season so there is something wrong if a striker fails to score score under those circumstances.
It is not a question of hating Ugbo just being realistic about his contribution. It is a shame as it seems he is a popular member of the squad which I doubt he would be if the other players felt he was not putting in the effort.
