These are the first pictures of Lassana Diarra as an Arsenal player.
The French international moved from Chelsea just before the transfer window closed on Friday. Arsène Wenger, who had not expected to add to his squad last week, explained how Diarra's late switch came about.
"He was only one year to go at Chelsea, and when he didn't extend the contract I thought, he's a player we rate, so it happened very late. I would have thought that in the end Chelsea would extend his contract but when it didn't happen we found an agreement with Chelsea."
Take a look at these pictures of Arsenal's latest signing.
