On the bolded bit are you saying Silva got quicker after moving to City from Monaco?
@JPRouve thoughts?
I recall thinking they got an ace of a player on their hands, who had deceptive speed due to his elite ball control, low centre of gravity and ridiculous stamina; I don't think that's really changed unless we're talking about Guardiola's Barcelona doctors?
To go back to the Ronaldo comparison, I think Garnacho has similarly great straight line speed but not elite dribbling/change of pace speed when needing to take players on from a standstill (as it requires a different skill/mindset). Whereas, Nani always had that great first AND second step of speed but only used it properly later when his game matured like you said as he realised it was more effective; it also helped that he became bit of a beast physically as well.
In my mind, I think Garnacho can improve as a dribbler/wide player but it will be mostly mental (off the ball runs, less touches, one-twos etc) rather than him gaining an extra step.
