For one, United is very likely to receive a sizable bid over the summer, perhaps from a team like Paris Saint-Germain. From David McDonnell of the Mirror:
Zlatan Ibrahimovic could leave Paris Saint-Germain—paving the way for a £35 million bid for Manchester United's Wayne Rooney by the money-bags French side.If I were Manchester United, I would want £45 million, and definitely ship Rooney to Paris for that sort of money. For £40 million, I would probably be persuaded as well.
Ibrahimovic is said to be disillusioned with life in France after less than one season, and could be ready to move on this summer to what would be the eighth club of his nomadic career.
That would leave the mega-rich, Qatari-owned PSG free to raid the Old Trafford club for Rooney.
Yes, I know Sir Alex Ferguson already said Rooney would be sticking around this year. I've also learned to take what managers and front-office people say regarding personnel with a grain of salt.
Honestly, did you ever think Rooney would be on the bench to start a game like last week's Champions League match against Real Madrid? Did you ever think a player of Rooney's class would spend his time watching one of the team's biggest matches of the year?
Of course not, but it's become apparent this year that Rooney is expendable.
He's still darn good, but for United, he's expendable.
Should the Red Devils sell Rooney this summer?
Don't get me wrong, I'm not saying United should actively shop Rooney. The man is still one of the more dangerous players in the world. However, for the right price, I think the Red Devils should sell him. There's no question about it.
See, I'm not crazy. It's obvious this year Rooney is no longer the best fit for this United roster. A lot can change between now and next September, obviously, but Manchester United must at least consider shipping Rooney out of town if the right offer comes their way.
