Arsenal youngster Alexandre Song has put pen-to-paper on a long-term contract with the club.
The Cameroon international joined the Gunners on a season-long loan from Bastia in 2005 before signing permanently the following summer.
He has found it difficult to establish himself as a regular starter in Arsene Wenger's side, but made 15 appearances last season
The 20-year-old returned from the African Cup of Nations to feature heavily towards the end of the Premier League campaign.
He can play in midfield or defence and filled in at centre-back for the last five matches of the 2007/8 campaign.
Song will now be looking to make even more of an impact next term after being rewarded with a new deal.
