I watched Grujic playing for Serbia U21s yesterday. He played where Wijnaldum plays for us in central midfield. Picked up a yellow card really early in the game (3rd minute!) with a rash sliding tackle, and that limited his aggression for the rest of his time on the pitch.
Serbia played quite directly a lot of times, so the ball bypassed their central midfield often and he didn't really get too many touches. Off the ball, he looked to make runs often into the box when they attacked; had a shot opportunity blocked, and then missed a clear headed chance which would have put them level with Portgual. When he did get the ball, he showed good first touch and often played the ball quickly, both short and out wide into space for the wide forwards or full backs to latch onto.
