Doubt he'd want to go, even if I don't believe the rumour. He seems to prioritise sporting success above money, and there's no way Man U's project is better than what he has here. Assuming they do offer enough of a pay rise to interest him anyway.
I don't think Alexis can provide much pace for anything in 2024. If anything, he tends to slow down the ball in transition cause he holds on to it longer than he should. He still has a good work rate, though, but so does Arna.
