I was bemoaning the Nico swap at half time as I thought we needed an attacking tweak not a defensive one, but that substitution changed the game. The kid WAS the attacking tweak, I just didn't appreciate it before I saw it.
As for Grealish, I love that lad too. I don't think the people on here who keep saying that he brought us stability by retaining the ball BUT wished he'd shoot more often, actually get it. The stability came because he doesn't lose the ball, because he doesn't shoot, and because he doesn't seem to mind getting a little whack as long as he gets a free-kick for his troubles. He's learned a lot since joining us IMO.
