Arsenal are reportedly confident that Shkodran Mustafi's arrival at the Emirates Stadium will help keep Mesut Ozil in place for the long term.
Ozil still has two years left to run on his current contract, but Gunners chiefs are said to be keen to agree fresh terms in the coming weeks.
According to The Mirror, the midfield ace - who joined Arsenal three years ago today - has been reluctant to put pen to paper so far as he waited to see just how ambitious the North London outfit were in the transfer market.
It is suggested that the signing of Germany international teammate Mustafi, a close friend of Ozil's, could tempt the 27-year-old to commit his future, while the £90m splashed out during the window is another step forward.
Ozil has already discussed a new deal with his advisors, which is thought to be worth around £200,000 a week, with Alexis Sanchez currently in an identical position with two years to run on his contract.
