The million dollar question, I think ten Hag would suit the clubs philosophy the best, but the last manager to come from Ajax to the league didn't exactly do very well.
I get the Poch rumour, he's a safe bet, been in the league, kind of competed, players improved under him, and he uses young players. I wouldn't be massively put out by Poch, but I do doubt if he has the extra bit needed. Maybe a league win in France will help him.
My main problem is I think we need someone now, not this interim rubbish. If it's going to cost 10m then so be it.
In an ideal world my choice would be Flick, never going to happen though.
