The 31-year-old, who missed a large part of last season with knee ligament damage, has agreed a two-year deal at the Emirates Stadium after nine years at Old Trafford.

With his contract set to expire next season Silvestre had been linked with a move back to his native France, but has opted to move to north London.

Silvestre joined United in 1999 and won a host of honours including four Premier League titles, an FA Cup winner's medal and a League Cup winner's medal, making a total of 361 appearances for the Red Devils.

On signing for the Gunners Silverstre told the club's official website: "I've spent a large part of my career at United, the last nine years, and I'll remember that time fondly but feel I'm ready for a new challenge.

"Arsenal is known for playing technical and skilful football, and has a young but experienced squad. I'm really excited about this next stage of my career, hopefully playing my part in helping the Club to new successes."

Arsenal manager Arsène Wenger said: "We have a strong squad but a young squad and Mikael's versatility, experience and calibre will provide the extra depth we need to reinforce our challenge for honours this season.

"His defensive adaptability will serve us well and it's a big plus that Mikael has top level experience and a great understanding of football in the Premier League."

Silvestre looks set to go in to the Arsenal squad ahead of the side's Barclays Premier League match at Fulham on Saturday, and will wear the number 18 shirt.
