Eh, no one would have a problem with Memphis if he just kept a low profile and focused on honest hard work. Instead he was showing off in brand new Rolls and banging 3rd grade gold diggers, to the point that Giggs out of all people had to reprimand him about his lifestyle.
If you act like you're hot ****, but done nothing of substance on the pitch, don't expect fans to have patience with you. People have patience with players who look like they're actually interested in improving their craft. If you cost 25 mil and the biggest headlines you make in your first year are of your exploits on the local celebrity scene, what kind of message does that send?
Contrast this with De Gea who came at similar age, struggled badly ,but he stayed humble, showed obvious talent and people stayed patient, helping him get where he is today.
