Problem is how many of those actually get their chance with the first team, i don't need to mention the likes of Carl Finnigan, Lewis Guy and others who were all so highley rated when they were in the reserves but are playing in places suchs as Scotland and the lower leagues, i used to hear so many good things about Johnny Godsmark but now he seems to be on his way out too, the only two who managed to made the step up are David Edgar -that of course helped greatly by his goal against United- and Andy Carroll who's height and physicalty were key to helping him make the step up.
Personally i wouldn't be getting my hopes up on a player who's playing well on the reserves untill i see him play with the first team.
