I've got him untradeable and didn't recognize it first, but after I did, I pulled him directly into my main team and he was awesome (before and after the upgrades, for sure).
He is tall enough to win many headers, is great at sliding tackles, can hold the ball, can pass and have nice work rates. I play him next to De Ligt (IF) or Pavard (MOMENTS), but he works also next to other defenders, like Konate (Gold), Lacrouix (Gold) or Dias (Gold) (all tested). The best about him and I dunno why is, that he changed alot of games for me, after I got corners around 85+ - he got the ball and I just shoot and he hitted the goal, even with his low sho-stat.
