I am sick of peolpe always using comment's as "he is only young" and "he has time on his hands", if players aren't performing they should not be on the pitch, I am not talking about Muamba in particular. Over the years players have been tagged with the above comments and never seem to reach there potential, one in my eyes is J.Jenas at spurs not always in the first 11 at a very average spurs team.
How much time do you give young players I just don't know, look at Kevin Nolan if he had reached his full potential he would have been England captain now but he peaked at the age of about 22-23.
