The German has been sensational for Arsenal this season, on course to set a new Premier League assists record, and his team-mate says he owes it to being happier off the pitch
Ozil is on course to smash the Premier League assists record, currently held by Thierry Henry, having created 16 goals already this season, despite initially struggling to adapt to English football.
The World Cup-winning playmaker failed to live up to his £42.5 million price tag in his first two seasons at the club, but is now finally showing his full potential.
Flamini believes the key to Ozil's turnaround in form has been settling in off the pitch and striking up close bonds with himself and others, which has allowed the German to flourish on the pitch.
"We are close friends and we have a good time on and off the pitch," Flamini told Arsenal Player.
"That’s very important because, if you want to be able to perform, you have to feel happy in your head and feel confident off the pitch
Flamini has played with a host of football legends in his career, including Ballon d'Or winners Andriy Shevchenko, Ronaldinho and Kaka, and says Ozil is every bit as good.
"We all knew he was a top player but I’m glad he’s proving it every game. It’s very important to have him on our side because, as you can all see, he can make the difference at any time.
"He has been giving so many assists and has been making so much difference in the past few games, so it’s a pleasure to play next to him and it’s also a pleasure to watch him on the pitch.
"His vision is something that you don’t find very often, so he’s easily one of the best players I’ve ever played with."
