Arsenal have re-signed midfielder Mathieu Flamini on a free transfer following his departure from AC Milan this summer.
The 29-year-old, who spent four years with Arsenal before his 2008 departure, began training with his former club earlier this summer when his Milan contract expired.
And Arsene Wenger has been impressed enough to make Flamini his second close-season signing.
"We're very pleased Mathieu has agreed to rejoin us," Wenger told the club website. "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 is comfortable playing in defence too. He is a very good addition to our squad."
Flamini's arrival follows that of his fellow Frenchman Yaya Sanogo, also on a free transfer.
Wenger is still to spend a penny in fees on new faces despite the "escalation in financial firepower" reported by chief executive Ivan Gazidis back in June.
