You are right about the fact that vs good (especially dynamic) opponents he has a lot of trouble, but honestly I think thats not because of his MENT. In my opinion that more because he simply doesnt have the skills to cope with very dynamic opponents (not fast, not strong, cant force the opponent back by going forward himself, because he sucks in that department). He doesnt have any footballing ability. Well, he is more De Graafschap level, then Twente level if you ask me, but its just his alertness, focus and MENT what keeps him good enough to play as a DM/CM in a top team in NL.
Could you see him play at any top 9 team in the Eredivisie? To be honest I dont. He has a lot of credit for being a fighter, and a local hero in Twente. Also he is one of the rare type of midfielders who can keep his focus solely on defending when he needs to (and he needs to when Adriaanse decides to play with 2 attackers on the midfield haha).
I dont really agree with you on the passing, because I think his passing is quite poor when he is put under pressure (I think it could even be lower). Yet still normally his passes are really safe (because they are "easy smart") and I think its actually a decent ability of him to find his team mates (what should reflect in decent TW, right?), but I agree that 85 is too generous.
Gave him an update. Let me know what you think:)
