the problem with all of that is the kids age - he is still only 15 - and for the Champions league he will only reach the required age allowed to play in the Champions League around the time of the next game so throwing his toys out of the pram right now is a transparent excuse that he is just a mercenary ar5ehole, and he seems to think that everyone else won't cotton onto this fact
you are only allowed to sign professional contracts at 18 and United have already had a few bigheaded entitled cants going through their academy - the last one was Garnacho and see what's happened to that tw@t now - he is no longer considered the second coming of Christiano Ronaldo but more like a pimple faced spotty youth still sucking his thumb who is actually a stranger to football pitch because the clubs he lands at are all making his shorts shine the bench
United have been though loads of teenage "next big things" who landed up being zero's instead of hero's because they were treated like they were too good when too young - Pogba, Rashford, and Frederico Macheda as well as Garnacho all come to mind as players who started off like a house on fire but who finished off worse than damp squibs in the long run of their actual career with one or two semi-spectacular years inbetween ..... and with this guys attitude he is heading there too but at Barca or Real Madrid the marketing machines will turn him into the next Mbappe even if he doesn't match the results and to be brutally honest - i'm still not yet convinced - the guy hasn't even played seriously in a real position in the senior side and everyone is already drawing conclusions about his potential ...... sounds exactly like Garnachos trajectory where everyone was touting him to be a mixture of Jesus Christ and Christiano Ronaldo but he turned out to be a lot of ar5e that clubs are regretting paying big fees for
only thing is with Garnacho we got revenge over Chelsea for them selling us Mason Mount when his career was more-or-less over - the guy (Mount) just cannot come back from his long term injury and Chelsea charged us big bucks for "in case he gets over those injury issues" well Garnacho still plays like a circus clown while we charged Chelsea the "in case his attitude comes right with another manager" fee so that was one useful thing he landed up doing for us ie got us some cash for utter dross
let this kid go and IMHO if Rashford still tries too hard with no results let him go too because his attitude was exactly a mirror of this kid but slightly a bit more discreet so the general matchgoing crowd was more on his side but all these socalled prodigy kids all land up just being entitled arses throughout their careers without ever understanding that they are only "legends in their own minds"
