I play a really atacking formation with Moussa Sissoko as my only DM. I have to say he performs great, I hugely depend on him. He is strong and not slow at all.
Dont accept miracles from this guy, he will do his job and do it great. He will get the ball and pass it. Also he has a high Pass and tackle rating per game
There are two things i really haate about him, the first is he gets booked a lot no straight REDs but a lot of yellows.
The second is He loves to take Longshots and i mean a LOT, the thing is he fails at it. I asked him alot of times to stop doin that and he rejected. eventually i learned him to look for a pass rather than a shot and he performs better.
