Over the 2007–08 season, Song started at centre back for Arsenal's League Cup matches, but missed their semi-final elimination by Tottenham Hotspur while away with Cameroon at the Africa Cup of Nations. He also started at centre-back in Premier League matches towards the end of the season, most notably in Arsenal's crucial visit to Old Trafford against Manchester United, while regular starter Kolo Touré filled in for Bacary Sagna at right-back.
