Yeah, and they're still ahead of us, with far better squads and good managers. And we can't buy who we want this window. Your argument is to spend money on senior players that we don't want. Just to 'strengthen' competition. But getting in players that just aren't any good doesn't help. It makes more sense to save the money, and play kids who, admittedly, generally also won't be good enough, but are a hell of a lot cheaper.
Kids get older every year mate. Eventually they become adults. And sometimes then they're good enough to play in the Prem. When they weren't before.
Because they were children.
