It's going to be a battle of which manager actually makes the obviously correct decision. Liverpool will need to start the match with a midfield 3 of Can, Milner, and Henderson. Somehow I'm not sure he does that though.
It's really not hard to get a manager to spend money. Wenger doesn't run the club. If the owners wanted Benzema so badly, he'd be an Arsenal player and Wenger can deal with it or fug off. There is more to the story than Wenger just doesn't want to spend money. Makes 0 sense. It isn't his money. I think there are tons of overpriced cars on the market, but if someone told me they'd pay for it, I wouldn't give a fug.
I think there is a lot more to the situation than Wenger not wanting to spend. It's not his fuging money, why the hell would he care to spend it? If you can't score and the owners/board have the cash, you buy a player. I think there is a lot more of a divide between Wenger and the owners than just Wenger doesn't want to spend money that isn't his.
