Ozil has been linked with a move away from Emirates at the end of the season in recent weeks due to his lack of regular first team football at the club.
The midfielder has fallen out of favour at the North London club since Arsenal manager, Unai Emery, took over from former Gunners boss, Arsene Wenger last year.
But Sogut has now said that the 30-year-old playmaker will not leave Arsenal before the end of his contract in 2021.
Speaking ahead of Arsenal’s Premier League fixture with Burnley on Sunday, Sogut told Turkish-Football: “Rumours will always persist, – there is no doubt about that – but one thing I can guarantee is Mesut’s loyalty.
“His mind is focused on Arsenal, and Arsenal only.
“He’ll be staying at Arsenal until at least 2021, and the fans need not to worry about the gossip that may come this summer.
“He has found a place he feels welcome and believes he has a lot more to give.”
