So you spend £100m on a flair player but then want to muzzle his "natural strengths"? That makes absolutely no sense. And if that's what City did do, with the understanding that's what Pep intended, it was a really stupid move.
I'm going to try and have some faith for a bit longer that City did know what they were doing buying Grealish and that Pep has a plan for him that will see him able to utilise his strengths and justify the price City paid for him. I'm sure no one wants that more than Jack himself. Presumably they know at least part of the problem is the mismatch with Cancelo, which is why they've been trying to buy a LB to overlap and also do a decent job defensively, which will free Jack up to do his job, rather than having Cancelo in his space and also have Jack spending half his time on the pitch doing defensive work covering for Cancelo. (Surely I wasn't the only one to notice Jack was the one winning a ground duel with Salah yesterday in the LB's area of the pitch?)
