Both players are out of contract in 18 months and want bumper pay rises to extend their deals.
Ozil has claimed he is waiting to see what Arsene Wenger does, with his future uncertain, before signing up.
While Alexis wants parity with the top earners in a deal worth around £250,000-a-week.

And Henry hopes the club is able to sort both out.
“It’s a difficult one, we actually don’t know what’s happening behind closed doors,” he said on Sky Sports.
“You don’t know exactly why it’s not been done yet. Mesut Ozil came out and said he’s waiting on the boss to see what he’s going to do.
“So who knows. We can only speculate. One thing I can say is you need to secure those guys. They are the future of the club.
“If you bring someone else it’s going to take another two years maybe for the guy to adapt to this league. And if you lost those two guys you might not have big guys coming to play around those big guys because they’re not there any more so who knows, they have to secure those deals though.”
