19 year old players don't develop by sitting on the substitutes bench. That excuse is paltry. Rooney, Ronaldo, Fabregas and Messi weren't sat on the bench at that age, and neither were many other players now currently near the summit of the game. Januzaj should be playing fairly regularly and if and when we finish top four this season, Van Gaal should be doing all he can to build the team around him going forward. We have an exceptional talent at the club and we should never be left to wonder what if. I'm not worried yet, though, I just don't agree that rest is best.
