Arsenal's Kolo Toure has admitted he does not get on with former skipper William Gallas.
The Gunners' central defenders have formed an impressive pairing again of late with the Arsenal rearguard conceding just five goals in 15 games, but Toure says his partnership with the Frenchman is purely professional.
The Ivory Coast international said: "My relationship with William has improved, but it's just a professional relationship.
"Once we are on the pitch we try to keep a professional attitude and to communicate."
Toure added: "I am friends with Johan Djourou, with Emmanuel Eboue, with Gael Clichy, but it is not the same with William.
"We never got on well together.
"However, it is the same within every company - you cannot be friends with everybody."
