Moving the ball too slowly. There isn't going to be gaps in a back 5 behind a back 4 if we don't move it quickly.
The gaps we do find are out wide, but we have little threat in the box from standard crosses with just alvarez against their 3 centre backs so it's down to the wingers, they either need to be hitting the byline and smashing it across or considering they're both inverted, cut in, take a man on and get a shot off. Grealish doesn't offer that threat at all and is pointless, Bernardo can do that but he's not a winger. Grealish off, foden on.
