The Daily Mail says Song is considering his international future after being booted out of Cameroon's squad to face Senegal over a bust-up with skipper Samuel Eto'o.
The midfielder had only just returned to the international fold after a series of snubs in the aftermath of Cameroon's disappointing World Cup 2010 campaign.
He has a fractious relationship with Eto'o and their feud came to a head this week when Song refused to shake the Inter Milan striker's hand. The pair then had a row when Song sat in a chair Eto'o claimed was reserved for him during a meal, which led to Cameroon manager Javier Clemente expelling the Arsenal player to avoid further disruption.
The Cameroon Football Federation later claimed the Arsenal man had left the camp due to injury.
