This card is honestly a monstrosity. There are times i prefer him to the David Alaba positioned next to him. For such a low rated and fairly cheap card he is a must for any starter team, if you can link him in.
Pace, he is fast even with basic. Running a shadow on him is ridiculous.
Defending, his tackling is on point. Stand or slide he will win the ball, he doesn't get turned much and seems to be able to keep up with the fast agile strikers frighteningly well.
Dribbling, as a cheap CB his dribbling is OK
Passing, again as a low rated CB no issues.
Physical, he seems to play above what his cards physical suggests. He has out muscled every ST I have played against so far. Love it!
Link to Zakaria, while he has his issues he is not a bad card. A good link with Burki and Meunier too makes the start of a pretty good starter team. Later on it might get tougher.
There isn't any to be honest, not that I can think of. Use him, enjoy him and move on when you're ready.
