He told the Mirror: "There would be nothing cooler, I've never experienced it over here, to win the championship of the Premier League. Some of my American cohorts have experienced that and we haven't been able to.
"I'm not getting any younger. It's something I would like to achieve. There would be nothing more thrilling than to win a championship.
"What a great player (Ozil) is. His spirit is great, the players who are with him... you can judge a lot by what players say when they leave and they weren't happy when he left (Real Madrid).
"We stayed in close touch as we went through the process. Everyone wanted to get him, other teams wanted to get him and to get him here is fantastic.
"We weren't there to make a statement. It's absolutely not done for that. It was done purely because our manager views him as worth that money, sees him as a player to help us compete, and that meant we were happy to pay it.
"There's an awareness financially within clubs of spending in the US and Europe or whatever which you have to have. But we've always said that there are resources available to Arsene. We have always been, and will continue to be, very supportive."
