Mathieu Flamini says he has some “unfinished business” at Arsenal after returning to the Club this summer.

The France international spent four years with the Gunners from 2004 to 2008, during which time they reached the Champions League final and came close to winning the Premier League.

"It's a great feeling to be back. Once you're a Gunner, you're always a Gunner" Mathieu Flamini

The versatile midfielder is determined to make an impact during his second spell in north London - starting in Sunday’s derby against Tottenham.

“It feels good to be back home,” Flamini told Arsenal Player. “I have some unfinished business with Arsenal so it's a great feeling to be back. Once you're a Gunner, you're always a Gunner.

“Unfinished business because we had the opportunity a few times when I was there to win trophies and we didn't. I'm thinking about the Champions League final, the 2007/08 season when we were in the running for the first place and we didn't close it.

“I feel good, I have been training for three weeks with the fitness coach, Tony Colbert. So I feel ready to start competing for Arsenal, especially on Sunday - it's going to be a big game.

“It’s a derby, everyone knows how important it is. We have to win it and we have to be ready for it.”
