Disagree on Diaz. He is decent at getting past players but nowhere as good as some of the top players. His numbers regarding that dont have him at the top table either.
His numbers at Porto did, though, and that’s why numbers can be difficult to predict sometimes, especially for something like dribbling. Diaz can dribble, he was widely seen as an elite dribbler, ball carrier and someone that could beat his man at will in Portugal, he also has top speed and acceleration. For me the issue is tactics and how we play rather than the player himself. We’d all love the next Doku (I wanted us to sign him before City), but one of the reasons Doku is so brilliant is because the structure of City’s play revolves around getting him isolated 1v1 against full backs: the movement, the probing, the constant recycling of the ball, the switches etc it’s all to get him isolated, just as it was with Mahrez, with Grealish and Foden when he played more wide.
I think if we want speed and ball carrying someone like Rafa Leao ticks a lot of boxes (a lot, not all) but I’m not sure on the mentality, whether he’s someone that’s going to be a dominant player or whether he’s more like a Rashford, good in moments, the odd purple patch followed by periods of invisibility and fans questioning his will to be great.
