"The downside of being a professional is you rarely get a chance to go to watch other teams so I’ve never actually been to the Emirates. But one day I will, hopefully.” Will Florentin and Paul swap shirts at the end of Saint-Etienne's game against United?“I’ve never asked a player to swap jerseys at the end of the game, although I do have some because when I’ve played against friends we’ve just sort of swapped spontaneously," Florentin added. "I think that after this game there’ll be a quite natural exchange of shirts.”Florentin's twin brother Mathias Pogba currently plays for Sparta Rotterdam in Holland.
