It's hardly been aimless. That's what Shola and Loven have been doing for the last few weeks anyway so you have no point.
Ranger charges everything down which is a great thing, but it's no use if your fucked after 30minutes and can't score goals. He can potentially be a decent player, but he has a lot to learn. He could learn a great deal from Lovenkrands and his movement if he want's to be a good player.
