Who realistically would buy him? I think Mourinho's interest a few years ago was not genuine.
He is still a money maker for Utd and with him on the brink of being Utd's all-time scorer and nearing on the prem's record the Glazer's probably will want to keep him. If all things were equal however, I would sell him immediately because once he is on the field the attacking play goes through him and I am sure Benzema, if he indeed comes here, will have one of the worst seasons of his pro career. Both rooney and Mata look to score for themselves and do not creatively link up with No9s. Some will say Rooney linked up well with Wellbeck but how about, Saha, Berbatov, RVP and Falcao?
In Europe we would have to compete against Barca, Real, Bayern, Juve and PSG and when I look at their style of play and the individual skill of their attacking and midfield players what chance to we have with Rooney as our main man. Benching him would be ideal but I suspect the chaos that would cause in the media and stands could put undue pressure on our starters.
Getting rid of him would probably be the best option but I doubt that is going to happen so be prepared for another 2 trophyless years.
