I would be very happy with him going anywhere in Italy. I think it would be the right level for him. AC Milan has Olivier Giroud trying to recruit him, too. Tactically smart, but not brutally physical in bad weather - i.e., the nature of football in England.
I would like to see Adams and McKennie play in England, for selfish reasons (TV coverage). I think Aaronson is good enough to stay there, too. But they need to be on teams where they all will play. Adams and/or McKennie could be great for West Ham's midfield, for instance, if Rice is likely allowed to leave. They need some younger legs.
Aaronson could bring something interesting to Aston Villa, or a team like Leicester, had they not also gone down. Maybe Brentford, especially with Toney unavailable until January. Crystal Palace might be a good spot for him, too.
I would like to see Yunus Mussah move to Brighton, as I have recently heard. He'd be a nice replacement for Caicedo, who is going to be sold.
