I wonder if Peter Bosz is considered, as a kind of out of nowhere bet.
Probably the biggest Cruyff disciple in top level management currently working outside of Pep. Basically built the Ajax team Ten Hag got so much credit for and took them to Europa League final against United with an average age of about 17. Failed at Dortmund, went to Leverkusen and did a pretty good job there for a while when they were in turmoil and he had to sell his best players. Developed Havertz and Brandt specifically. Now at PSV where he has been devestating, crushing all records last year. Over 100 goals scored in the league, hardly any goals conceded. Dominated Slot's Feyenoord. Started this season magnificently. Spanked Girona yesterday. Is bald. Plays 4-3-3 with two advanced playmakers and fast tenacious wingers with a big lad up front. Eredivisie is divisive, but clearly shown what he is capable of when he has players talented enough to win
