De Zerbi is the obvious one if that's an option. Looks a brilliant coach, ambitious, fiery, competitive. Good football, good English and hasn't looked out of place coaching in the PL. Spaletti has done a great job this year, but it's a down year in Serie A and he has the two best attacking players in the league. If you have a good team with top players it's an easy-ish league to do well in.
Pochettino is the clear favourite for the job in the betting, and probably in reality. De Zerbi would likely be a 15m buyout. I'm not against Pochettino thing, I think there's a chance it could go well. But he's a coach who built his career on aggressive, hard running football. I don't hold his time at PSG against him because that front three is so far away from the basis of his teams in the past.. but whether he on a personal and professional level retains the hunger and ability to really give all of himself to a group of players in the way he did 7/8yrs ago, and whether a group of players buys into that now, I don't know.
Tuchel and Potter, no thanks. Can't go ex Chelsea again even if both might be good appointments. Thomas Frank.. not for me,don't think he'd be successful at a top-ish club and should try to make as much success as he can at Brentford.
