Potters got proven continental success (admittedly at a lower level in Scandinavia) on his résumé, so would be a good call. Still think there is a good coach in there and would largely ignore his blip with the Xhavs.
I think he's a top coach, just decided to take charge of Chelsea at one of the worst possible moments. Tuchel, him and Poch have all struggled over the last 18 months since Boehly took over. The bloke's played real life football manager and found out 72 new signings aren't going to gel instantaneously, regardless of what manager you have.
Ajax could be a great fit for Potter though.
