I like the balance of Grealish left, Foden right.
Foden left, Mahrez right also works pretty well.
But Foden can't play all the time and that means sometimes we get Grealish left, Mahrez right, and the balance of that is off.
Grealish left, Alvarez right might work, but I don't think we're likely to see it often.
Anyway, thought Jack did pretty well tonight. Tough match all over the pitch once we were down to 10 men but his ball retention helped us get out of a passage of play where we kept giving it away. Looked to drive forward when he could but limited options ahead of him because of the red card.
The partnership with Cancelo still isn't fully comfortable, they occupy the same positions a lot, but I could see him adapting to that on the pitch, moving infield when Cancelo went wide. It's not intuitive yet but give it time.
Had to be taken off when he was though as along with KDB he looked knackered.
