This West Brom game showed me that there are certain players in our squad who must be close to their last chance at United. Anderson has been a colossal disappointment in his time here and Buttner has only ever impressed in his debut game.
Rio is having a terrible start to the season and Young and Valencia have been shocking for 12 months now. Lots of deadwood and underperforming players in the squad. They need to be replaced.
Meanwhile, you have Kagawa, Adnan and Zaha who all could do well given a chance (although Adnan would obviously need to be handled with care).
