You're pretty clued up on overseas football. Anyone there or on these shores that stands out to you as the one to go for? Do you have a few you'd be happy with? Are you happy with Unsworth to go with it for the season?
In a vacuum, I like Tuchel. I just don't know if he's a good fit, mostly because I have no idea what the balance of power is between Moshiri/Kenwright/Walsh/the manager. I think I'd want a more organized backroom structure before making a play for someone like him.
As long as he continues to come up with coherent game plans and motivate the players, I think Unsworth is the best choice for the rest of the season.
