The Guardian says Song has caused irritation at Arsenal with his desire to explore his transfer market options in the face of interest from a clutch of leading clubs, including Barcelona. The midfielder has been made aware that he is in demand after a positive season last time out and he wants to listen to what is on offer.
But his stance has gone down badly with the manager, Arsène Wenger, and the board, who feel that Song ought merely to have ignored the approaches to his representatives and continued to show gratitude for what the club has done for him. Wenger took Song as a teenager from Bastia in a deal that was initially worth £350,000 and has developed him into a defensive midfielder of repute.
The friction has built to the point where Wenger has questioned Song's worth to the team and even wondered whether he may sell him if a large offer were to come in. Arsenal have not yet received any official bids.
