Maybe, and you may very well be right here, but that doesn't explain why he just doesn't run at defenders at top speed anymore. In the past, he used to run at players and flick it on the outside at pace leaving defenders for dead. Nani was always quicker off the mark, imo, than Valencia is. So many times Valencia has been isolated against his fullback with the option to simply flick the ball twenty yards ahead and run past his opponents, at pace even, yet he refuses to try this. That is what I cannot understand. Valencia never had quick feet the way Lennon or Sterling has, but he would destroy both for top speed over a distance. In close quarters he was never the best, but he's lost the ability to run at people...
No worries mate - I'm hopeless that way myself
