Yet he'd played well against a far superior PSG side, but that was in a back three, and I assume was given the task of watching Mbappe, because of his speed.
I don't think he was any worse than any other United player on that night, the whole team seemed to be in a 'we are superior' mode, and didn't try to win the battle before using our abilities to beat a poor side, similar to the way we seem to come out against the likes of Sheffield United, West Brom and Fulham.
Yes Tuanzebe has a lot to learn, and yes, he struggled physically in that 1 x 1 against Ba, but on Thursday I was waiting for the times when he switched off, but to his credit he seemed 'on his game' for 90+ minutes, which is the first time I'd seen that from him, so perhaps his concentration levels have improved.
He certainly has the physical attributes to perform at the highest level, but needs the experience.
If we do sign another CB, then perhaps a season loan to a prem club may be a possibility, but personally I would like to see him get more minutes, especially as both Bailly and Lindelof appear to have ongoing injury issues.
