Don't drop OZIL he is a 7 star player and he is also doing good...You are the best judge of your players...Its you who have to decide whom to play and whom to not play...
Playing a performing 7 star player is more advisable than playing a Counter Formation......
Play the 4-5-1V formation but instead of AMR play OZIL at MR...It will also give you some benefit in possession as your opponent has a strong mid field...
