The 20-year-old joined Arsenal on loan at the age of 17 from
Bastia in 2005, making the move permanent a year later.
He was loaned to Charlton for the 2006/07 season but was kept at
the Emirates last season, making 15 appearances.
He impressed at this year's African Cup of Nations for his country,
a key component in their midfield as they made it all the way to
the final before falling to winners Egypt.
However, he has been less impressive at club level, as Arsene
Wenger often persists with him at centre-back, which is not his
natural position.
He has nevertheless done enough to secure a new deal, with Arsene
Wenger denying claims that he was a bad buy, going as far as to
ensure he will become a great player, quite possibly at
centre-back.
"I believe he is a remarkable player and I was one of the very,
very few who believed in Alexandre Song," Wenger said.
"I can show you articles in newspapers which said that [he] was the
worst buy I have made but you will see in one or two years that he
will be a great player for Arsenal."
His extension has been described as 'long-term', with none of the
details having yet been revealed. He joins Bacary Sagna, who also
signed an extension last week, with Cesc Fabregas reported to be
next in line.
