See, that offer would maybe possibly be acceptable. Not like the offer that some braindead United fan posted in the thread re: this on the Everton subreddit saying Rooney + 15 million for Lukaku.
The way I see the Rooney situation is he was a boyhood blue, helped us get out of the slump we were in in the late 90's/early 2000's and was more or less sold out of necessity rather than him not signing a contract because he wants to leave (see: Lukaku, Romelu). He'll make a good coach to Barkley and the younger players, and will probably make a good squad option. An aging Rooney as a sub striker is still better than Arouna Kone.
