The 30-year-old Barton was sent out on loan by the London club in disgrace last summer following his red card shame at Manchester City, which brought him a 12-match ban. But Barton has flourished in France where, after being made to serve his ban, he has quickly become a key cog in a Marseille side in a three-way tie with Paris St Germain and Lyon at the top of Ligue 1.
And Anigo insisted Barton's impact had come as no surprise to him and he told L'Equipe: "He was described as an animal, but he is just the opposite. He is funny, intelligent, and he fights for victory."
He added: "We can see that the team has been lifted by his competitive spirit. He is now established as a leader in our group.
"He is very happy here, maybe he has found the right club for him. Should he desire (to stay) it could be very good. We have a very good relationship with his club QPR."
