Mathieu Flamini
Mathieu Flamini has been confirmed as Arsenal\'s second summer signing.

Arsenal have announced their first senior signing of the summer with the club confirming that Mathieu Flamini is heading back to the Emirates after signing a three year deal.

After spending four years with the Gunners Flamini made the move to AC Milan in 2008. His time with the Serie A giants brought mixed success and after coming to the end of his contract this summer the club let him go after reported disagreements over a new deal.

The 29 year old has since been training with Arsenal and it was believed that he may have had similar disagreements with the Gunners. But today the club were able to confirm that the Frenchman will play for the side this season after agreeing a deal.

Arsene Wenger told the official Arsenal website: "We're very pleased Mathieu has agreed to re-join us.

"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."

Arsenal fans have been calling on Wenger to sign players this summer after Ivan Gazidis revealed at the beginning of the transfer window that the club had a large cash reserve to spend on new players.

So far the north London club had only signed French youngster Yaya Sanogo, and whether fans will be pleased to see Flamini added to the squad remains to be seen.

Wenger is also believed to be targeting a number of Real Madrid players in the lead up to deadline day but as the sale of Gareth Bale to the club continues to stall it seems he is being made to wait and see whether the Spanish outfit will sell any of their players before the window closes.
