If you can get him in your team as a CB then do it. You will not find better for 150k.
I've not found him out of position so far in 5 games, the weak foot and stamina haven't been an issue (although no ET yet).
He is the most aggressive CB and seems to be on to the attacker very quickly if the ball can be won. I use pressure on heavy touch so not sure how he would fit in a passive or drop back defence.
Happily dropped Akanji and Roberto Carlos 91 to fit him in my team:
