I have used many RB's this year. Alonso, Kolarov, Sandro, Telles, Mendy as well as others. Alonso was my favourite but this guy might be stealing that spot.
Pace - This card doesn't look that fast, but his accel is fantastic, he can tackle before the opponent gets away.
Passing - Great passing, he takes corners and gets assists from there. Crossing is good too but he doesn't get forward for me (stay back while attacking, so by choice.)
Dribbling - nice dribbling to get out of hairy situations.
Defending - all round, tackling, heading, intercepting he is very nice.
Shooting - for those who attack he will score if he gets forward consistently. He hasn't for me but he has hit the post twice and both of them resulted in a rebound goal so he is great.
Stamina and Jumping - Great in the air and will play all game. I imagine even with attacking he will be fine for stamina.
Strength - The one flaw of this card is his strength. Vs attackers it doesnt show but when the opponents RB gets forward that is when it shows. Though with the Anchor less so.
Price - Expencive LB for reasons, but expensive none the less.
