Unai Emery will go up against one of his former players on Thursday night when we take on Rennes in the Europa League.
Our head coach was in charge of Paris Saint-Germain during Hatem Ben Arfa's time at the club, and knows what quality the attacker has.
"He’s a very good player and he’s playing with big performances," Emery said. "We know they have good organisation and good players - and one is Ben Arfa.
"We need to control his quality and his skills because in the two matches they played against Betis he played very well with big performances.
