The pair played together last season at Olympique Marseille.
Barton told L'Equipe: "I am still in contact with some of my former team-mates. I speak to Morgan. I really tried to get him here. I spoke about him to the manager, to scouts, but here we don't know the French championship. I said to them: 'He is a good player - get him over here'. They told me: 'We don't even know who he is.' So when he scored this weekend against Manchester United, I took the mickey out of them.
"I knew that in England, he would do well."
