Dude, what on earth is the matter with you? Read and understand context. The Messi part was only and only related to your over-exaggerated comment of a '12 year old girl', and nothing else. It wasn't a comparision to Messi or Januzaj's game or goal scoring abilities :\
And incase you're speaking down of a weakish player who gets taken down a bit too easily, we had one of those earlier too. His name is Ronaldo. And he improved. Just because he's on the bench, doesn't mean he'll automatically become bad.
Although, that being said, it'd be nice to see Januzaj being given more time.
Ignore him. He's not worth it.
