Unai Emery and Hatem Ben Arfa are experiencing an increasingly fractious relationship.

Ben Arfa signed with Paris Saint-Germain this past summer from Nice.

"You're no Messi," Emery is said to have yelled at Ben Arfa during practice. "If you were, I wouldn't say anything to you at all. You're not capable of winning a game all on your own like him."

Emery has left Ben Arfa out of his match day squad for PSG's last three games.
