Arsenal are ready to give the 24-year-old the green light to become the fourth player in five years to make the move from Emirates Stadium to Nou Camp.

Song is set to follow in the footsteps of Thierry Henry in 2007, Alexander Hleb in 2008 and Cesc Fabregas in 2011.

Barcelona were encouraged when their exploratory enquiries for Song were met with the response that indicated the player would be available for the right price.

The Catalan club had initially refused to meet Arsenal’s £15m valuation of the player, but sources have told Goal.com that a deal at that price has now been agreed.

Song, who joined Arsenal, initially on loan, in 2005, is poised to be granted permission to discuss personal terms with Barcelona.

He explained in the wake of the club’s pre-season victory over Cologne on Sunday that he was flattered by Barcelona’s interest.

"I am not going to lie if I said there is no interest but I am at Arsenal and I am happy at Arsenal," he told Sky Sports. "Barcelona are the best team in the world, and speculation will always continue until the window closes.
