It came across as if you were trying to move Axel into the same bracket of player as Upamecano, which was the basis of my response.
Even injuries aside, I don’t think he’s shown enough to be knocking on the door of the first team. Yea, he played 25 games at Villa last season. But to what standard? He was decent, he wasn’t building the sort of reputation that Henderson has been building with his performances. He was just a Villa player, but one who happened to have a United contract. Given we don’t typically go shopping in the Championship when looking for first-team players, he’d need to have been a lot better than he was at Villa (not that he was ‘bad’ at all) to say he should come back and get in the United team. It’s as if some fans wrote the whole story out before he left to go on loan, that he will ‘go out, get experience and then come back and fight for a place’ and his performances are the last factor they considered relevant from there on. For him to go to the Championship at 20/21 years old - he’d need to have one of those ‘he looks too good for that level’ seasons to be expecting to come back into our side. That wasn’t the case.
I reckon people will struggle to list 3 actual centre half performances at pro-level that they have seen from Axel that made them think ‘this is a future United regular’, but it’s still a such a commonly held view, at 22 and a half years old. If we can get Upamecano or similar quality for £40m, I wouldn’t be surprised if that’s only marginally more than we can mug a PL side for Axel, which would make it an easy trade for me. We have plenty of other academy players around to worry about losing the souls of the club or anything, we can’t start lowering the Manchester United bar for these kids.
