I can't sing his praises enough, he's an awesome manager. The football under him has been breathtaking for such a big part of his tenure, that is exactly where you want to be as fan of a big club, constantly winning, challenging whilst being entertained weekly with lovely football. If you watch Ajax' performances from 18/19 in the CL, EL, almost every game they are the better side and even against the top teams, they gave them such a good run for their money at least. Have had some bad luck at times, poor refereeing and also often poor finishing, but performance wise, just fantastic stuff.
I need to make something clear however. Sure, Ajax doesnt have the quality of United or the biggest teams in the world, but these arent pub players. These players all (apart from the keeper), have very specific qualities which suits the way Ajax wants to play to a T and are purposely chosen for it. Most of them have their limitations as well but many of these players have qualities that even our star players lack.
Mazraoui is outrageous on the ball, his feeling for space, two footedness, dribbling, link-up play is masterly. He's much better than Dest who plays very well for Barcelona from time to time as a starter.
Daley Blind, outrageous on and off the ball. Is rather slow but his positioning, ability to pass a ball forwards, find players between the lines, long passes, so good.
Timber and Martinez are relatively short and Im sure would be considered far too short to be United defenders. But they have very good timing, are very agile and mobile, great on the ball when under pressure, good dribbling and also long range passing.
Alvarez is what Fred should be for us in theory but he has far bigger physical presence.
Just to name a few, the likes of Tadic, Berghuis, Antony also have outrageous qualities that are huge for Ajax' play. Especially Tadic, the level he has had since his arrival, and how many things he constantly gets right every single match, I have seen that with very few forwards/wingers in Europe the last few yeads. The quality of Ten Hag is bringing all this together, making a machine out of it and continuously developing the players and tactics.
