Nobody even looks let alone tries to play him in any more. No balls on the deck for him to run onto. Ever.
He gets annoyed that he's not being looked for. He switches off and gets moody. After a while he doesn't make the run because, well, what's the point. And then he's got three defenders all giving him a dig.
Pep said last week, words to the effect of "if you've got Messi you don't sling crosses in, if you've got Haaland you do, because he'll score from them", now where were all those crosses tonight?
We don't play to his strengths, we actually play to his weaknesses, and then people moan that they're disappointed in "him".
Just my take on it.
