You probably haven't watched him play. So who is world class youngster? Neymar? Please, he also hasn't proved anything yet, just like Gael. Lukaku? He can be really bad sometimes. So then when player is 19 you already know how good he is going to be? He has still couple of years to develop. Leap from reserves into a Chelsea first team is not that easy as you think it is. Don't think that Josh will always play well!! I am used of hearing all sorts of shit coming out of Chelsea fans, when we are speaking about our youngsters.
