Arsenal legend Thierry Henry says Arsene Wenger needs to buy back Alex Song. Song is starring at West Ham United this season on-loan from Barcelona.
"Song would improve Arsenal," the former striker said. "That is the type of player you want in front of your back four.
"Song is the captain of the boat. He protects the back four.
"You need someone to dictate, put players into position, make little fouls by kicking someone - like Claude Makelele used to do."
