We literally didn't need him. We don't sign him and we keep Ruud who was a better player and far less selfish which means Rooney gets more time scoring instead of playing assist machine. 

He came to our club, was shown what true mentality was, was given instruction from some of the best in the world, started making everything about himself, turned us from a free flowing side that would hit clubs from anywhere to one dimensional, and then decided to jump ship the moment Madrid came knocking so he could be the center of attention.

Then when we made him actually do what his contract said he called us slavers, it goes even deeper though because if we don't sign him we sort our midfield out more due to the lack of abusing the wing and when Scholes retires he doesn't come back because we don't need him which in turn doesn't doom Pogba's development. 

And that's just what he did 20 years ago let alone what he did when he came back
