Yes, and a regular theme of this season has been us not producing our best football and often lacking the control that defined the biggest games of our treble-winning season. The best performances and runs of this current season have come during periods when Jack has been fit and able to contribute.
Let's look at our defeats in the league this season:
Wolves away. Grealish gets 10 mins.
Arsenal away. 0 mins.
Villa away. 0 mins.
And now let's look at our record in the league when Grealish has started:
W vs. Newcastle
W vs. Sheffield United
W vs. United
W vs. Luton
D vs. Palace
W vs. Sheffield United
It was like night and day against Copenhagen, the difference in our performance before and after Grealish went off. Just go back to the thread for the game. We were purring against Copenhagen and ripping them apart with Grealish on the pitch, as soon as he went off it become more of a contest and they got back into the game. We ran out winners in the end but it was a hard-fought game after Grealish went off.
You just keep trying to bury your heads when it comes to how crucial Grealish is to this team.
