Bernard and Bilyetdinov, although lovely touch players and talented, didn't have either of the physical attributes needed for the EPL. Both lacked pace and strength. JL has a lot of pace and, unlike someone like Walcott, he seems to have intelligent movement. It's not blind luck that he is finding space in behind opposing teams so often. He obviously needs to improve the end product to be a top player but even if he never does just having someone who runs in behind a lot will create space for others and help us to play better football. I think there are enough signs that he could be a really good player to be encouraged. He isn't perfect yet which is why he plays for us.
Good thoughtful post mate, like to see goals and assists come from him, but it's early days as yet, much better than Harrison, quite pacy and intelligent footballer, I think/ hope the best is to come.
