The midfielder says they are glad to have the Frenchman, labelling his two goals against Tottenham Hotspur as sensational.
The France international is in his second spell with the Gunners but finds himself filling a peripheral role at the Emirates, with Francis Coquelin first choice in the defensive midfield berth.
Flamini was expected to leave the club in the summer, with reports - such as those in the Daily Mail - suggesting that he was surplus to requirements. A move never materialised, though, and he remains very much part of the squad in north London.
And Ozil says his teammates are happy to have him as he remains a positive influence on and off the pitch.
“I have a really good understanding with Mathieu,” he told arsenal.com.
“He’s a guy who always gives 100 per cent on the pitch but when he’s off the pitch, he’s a player who gets on well with a lot of his team-mates. As I said, we’re just pleased to have him in this team.”
While he has struggled to break into the first team for the Gunners this season, Flamini did play a starring role in a recent Arsenal fixture.
Arsene Wenger drafted him in for the Capital One Cup game against Tottenham Hotspur in September, and he produced, scoring two goals to help his side secure a 2-1 victory and end the cup ambitions of their arch rivals.
The second of those goals was a well-taken volley from outside the area, and Ozil says both efforts were 'sensational'.
“He scored two wonderful goals [at White Hart Lane],” he added.
“He’s been rewarded for his strong showings and those goals were of course sensational. [Volleys like that] are really difficult. Mathieu caught his perfectly and scored a wonderful goal, especially because it was the winner.”
