It's things like this that would hinder the club from moving forward. It's like fans enjoy hugging history while the world passes by. Raul of Real, Xavi of Barcelona, Del Piero of Juventus; bigger legends and better players at clubs that essentially raised them did not have to retire there. When these players left their respective clubs, they were still performing at a higher level at Rooney in their mid thirties. These clubs have moved on replaced these legends and are way ahead of United footballing wise.
The right, If he wants? What the heck does that mean. Do we support Wayne Rooney or United? Because of what he has done? Why don't we keep Rio, Nev, Brown et al, they were part of United's golden era and by that should stay here!
A player should be at the club as long as he is actively helping the club progress on the pitch not just because of what he has done in the past like they did it for free and out of their generosity, the kindness of their heart and their undying love for the club.
