That's the reason I can't stand Ozil - he only plays well when the team are comfortable and in those games they don't need him because 9/10 they'll win anyway. But when it comes to close games he just goes missing completely, hiding from play. If anything he's more likely to make them lose because half the time they may as well play with 10 men. If I'm paying top money for someone it's so they'll make a difference in those close games or ones which need to be dug out or a moment of brilliance.
How on earth he still gets to go arond demanding the wages he does stupifies me.
