Former Arsenal midfielder Mathieu Flamini has returned to Emirates Stadium on a free transfer.

The 29-year-old France international was released by Milan in the summer.

Flamini had been training with the north London club in recent weeks.

Arsenal manager Arsene Wenger said: "He is a player of real quality, with a fantastic work rate and great mentality."

"As we know, Mathieu is a strong midfielder, but is also comfortable playing in defence too. He is a very good addition to our squad."

Capped three times, he made 102 league appearances during his first spell in London between 2004 and 2008.
