I think we're seeing just how important RVC was. We even looked blunt at the best of times last year but always had him to rely on. It will take time to adjust and find a new source of goals, you just can't expect to pick up where you left off by selling a player of his ability.
Same goes for Song but to a lesser extent.
Transition is a word that always pops up with us but I do think it's quite relevant at the moment, because Song and RVC were far more integral to us at their point of sale than Nasri and Cesc were.
