You can't really say Fabregas wasn't bought partly due to Ozil. Ozil hasn't even been playing centrally this season and Fabregas has played right next to Matic.
Everyone said because we have Jack, Ramsey, Ozil etc. who can all play in those position.
Ozil played wide to accommodate Ramsey and Jack.
2 players that Wenger would never sell.
That formation was also shit and I doubt we will see it again.
Wenger also said he didn't buy Cesc because he has Ozil, so yeah.
