Playing him wide when Suarez is out is borderline retarded.
Playing him wide is retarded.
But playing him in the middle is only 1% better than playing him wide.
If you play him as a 9:
1. he will drop deep to defend into our box and the most often won't be in the opponent's half
2. when he is in the opponent's half, he again likes to drop deep to some sort of a CAM position to create and pass the ball to "someone else" who is actually a NO9, like Giroud, Costa and similar
3. if he will somehow end around the box, if you give him the ball:
1) he will be tackled since he is insanely slow
2) he can't dribble because he is slow and can't dribble
3) plus, his finishing in the last year and a half is horribly inaccurate
Basically, the only use of him as a no9 are some simple tap ins, some loose balls into the box falling to his feet, some rare headers and actions when he has 20 meters advantage over defenders, so he will have time to run and actually try a shot without players tackling him.
In this moment, I would rather have Coutinho than him.
Coutinho at least could have dribbled and can shoot from 20 meters.
Griezmann can't do even that.
