I don't really get the logic on that one. How would Ramsey allow Laca to play a more advanced role? If anything a player like Aaron depends on centre forwards coming deep and playing the link role and providing him with the space to run into.
Secondly I dispute that he was ever a player who hung around the box, in fact it's always been a pet peeve of mine that he lacks the drive to get into scoring positions. Despite his awful form recently his goalscoring rate isn't much worse than last year.
I'm certain he'll get better and start scoring at his usual moderate rate again, and there won't be a grand reason behind it other than a player and team finding a bit of confidence.
