I definitely dont have the feeling he is playing out of his skin for a transfer... He has been very consistent for a long while now, also last year before his injury he was very very good.
There are two things you have to consider though which circumstances at Ajax are in his favor which wont automatically be there in a new team.
- He has a very very good understandig with Antony at right wing. You can see for both Antony and Mazraoui that when either is not playing, the other provides a little less threat then when they are on the pitch together.
- Mazraoui is definitely solid defensively: good pace, good position, good tackle, but what sets him apart as a right back are his technical footballing qualities. At Ajax he plays in a system which allow him to display those skills. He plays high up the pitch, has freedom to end up in midfield centrally or overlap his right winger (someone like Alvarez (dm) will be always there to cover), and gets the ball in his feet a lot. There is also almost always a lot of movement around him to give the pass. Ten Hag puzzles towards a team where all players play in their strenghts, Mazraoui being no exception. Im yet to see how he will perform when he gets into a team with less capable manager or a manager with a more frigid playing style..
