The 25 year-old Spain defender has been a key player for the Catalan side for the past four years and has stated that he believes the Gunners man would fit in well at the club
Following hot on the heels of similar declarations from both Andres Iniesta and Sergio Busquets recently, Pique has stated that he has been following the career of the Cameroon international for quite some time, and believes that he has the necessary skills to fit into Barcelona's style of play.
"I have followed his career and he has become a very good player," Pique told El Mundo Deportivo.
"He is physically very strong and is good with the ball at his feet. We are open to his arrival."
Song enjoyed an excellent campaign last season at the heart of the Arsenal midfield, as he went on to finish the season with 14 assists to his name across all competitions, but Barcelona are thought to be keen to keep the cost of any such deal down to around £15 million mark.
If Song were to move to the Spanish side, he would follow in the footsteps of the likes of Marc Overmars, Emmanuel Petit, Thierry Henry, Alexander Hleb and Cesc Fabregas who have made the same switch in recent years.
