Grealish is too slow on the ball. He slows everything down and is more interested in trying to draw a foul than stretching his legs and being direct. I just want to see him pick the ball up and run at defenders with pace.
What he's doing is the only sensible thing to do. As you say he tries to draw fouls. Surely you've noticed we're at our most dangerous from set pieces, especially in away games so I can't decide if this is something he's decided to do to give us a chance or if he's been asked to do it. I think Grealish is a very smart player so it wouldn't surprise me at all if he has realised that he just doesn't have the movement in front of him to influence games in open play so he'd rather get us free kicks and see if we can take advantage from those.
If he has the right players with the right movement around him I think he could be similar to David Silva
