gueye was one of if not the stand out player of the pre season games and then broke his toe and only just got back for the united game, if it wasnt for that injury im pretty sure based on his form he would be a first teamer 9/10 so far this season regardless of age and when he gets his fitness back 100 percent i see are future left winger and vellios is better than saha atm even if he is only 19 he may not drop as deep as saha or want to run with it from the halfway line but he does his job SCORE and saha is not and that is his job, if you were a journalist and you did no stories all month and a 19 yr old did 3-4 good ones he would get your job in a heartbeat. age has got nothing to do with it, its quality and end product that we need
