We need a big name or someone with a strong personality. I like Setien, but we need a commanding presence. Not sure he's that.
We should have brought Henry in as an assistant coach this season like Real Madrid did with Zidane under Mourinho and Ancelotti.
He's left his job with Sky and is an assistant for Belgium right now. He want to become a manager and is waiting for the right option. If things go bad we could have had him as a caretaker until the end of the season. Note: I'm not hoping it gets that bad.
Also potentially seen if he had the presence and tactical ideas and scheming to take over after Valverde. Unfortunately all the attractive options are gone and I don't like Allegri too much.
So we either go with Setien, one of our former Dutch players that are managers right now, or someone like Henry who's completely unproven.
