Rennes president Olivier Letang is looking forward to a reunion with Arsenal boss Unai Emery.
The pair worked together at PSG, where Letang was part of the front office.
Ahead of their Europa League round 16 tie, Letang says: "At PSG, we had cordial relations, but I was his interlocutor in a rather short way.
"He himself said: There was someone when I arrived and then it changed. It changed the situation. And then I took a step back.
"But I do not think that the fact that I know him is an advantage. Today, he certainly works differently than from PSG, with other players."
