I've packed him untradeable and thats why I use him in a BPL/Bundesliga-Squad (because I packed some players outta that leagues).
I played him as a RB and a LB and most of the time, he is very solid, but I also had matches, where he maded some mistakes and thats why I used the title I used.
When you see his stats, you think, he is very nice and sure, most of the time, he is, but I don't know if I would use him for that long, if he was tradeable.
