Asked about his pursuit of PSG fullback Sylvain Armand, Aulas said: "He is the priority for [coach] Alain Perrin. But it is difficult.

"There are other players on our list like [Inter Milan's Fabio] Grosso, a champion of the world, or a player from Manchester United."

United pair Patrice Evra and Mikael Silvestre have been mentioned as potential Aulas targets.
