I love ETH to death, probably my favourite manager after SAF, but he has flaws.
He sometimes refuses to give those a chance who are clearly shining. Maybe because he understands football is more than what you do on the ball and he wants all to fit together in the machine he is making.
Noa Lang was by far the best player in pre season 20/21, but ETH just refused to give him a proper go and he was sold.
Naci Unuvar was a huge revelation for Jong Ajax last season, and he just didnt get any look in at any point. He's a smallish #10 who might miss the stamina and work rate I guess.
On the ball, I think Amad is amazing. He works hard, he presses and is visibly getting stronger, he really could be like a new signing. The boy is just gifted.
