QPR midfielder Joey Barton intends to prove his footballing ability at Olympique Marseille.

Barton attended Marseille's 3-1 win over Rennes on Saturday and gave an interview in which he admitted: "I've been stupid, I have to change."

His new club have been quick to defend their loan signing and Barton insisted: "In France I'll be judged on my displays. It's time to stop talking and prove I want to play, to show I'm a professional. I hope to help Marseille succeed quickly this season."
