Mikael Silvestre is relishing the 'new challenge' of life at Arsenal, but will always have fond memories of his epic United career.

The versatile French defender won 10 major trophies in almost a decade at Old Trafford, but completed a move to the Emirates Stadium on Wednesday evening.

"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," he told the official Arsenal website.

"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."

Silvestre made 361 appearances for the Reds after arriving from Internazionale in 1999, but becomes the second defender to leave Old Trafford this summer, after Gerard Pique rejoined Barcelona.
