Sarri I'd be the most excited about, given what he's done at Napoli and the football they play.
Then again, as Luke mentioned, we have so many players that don't fit his methods. Having hard working technical central midfielders play a big part, and I'm sure Sarri wouldn't embrace the idea of having Drinkwater, and an ageing Fabregas in his team. I would however like to see what he could do with Barkley and Bakayoko
He should be the one in my opinion to go for, but as mentioned, he must be given full support. If not, we might as well put up a new website when the next manager will be sacked, as this will forever be a continuing theme should our board continue the way they do business.
Enrique is a gamble. Carlo would set us back tremendously.
