Following Mathieu Gorgelin, Corentin Tolisso, Nabil Fekir and Rachid Ghezzal, Mehdi Zeffane is the fifth OL academy graduate to commit his long-term future to the club
After playing eight Ligue 1 matches and five in the Europa League in the 2013-14 season, Mehdi signed his first professional contract to 2017.
"I was really hoping for this moment. Signing until 2017 is a great sign of confidence by the club and gives me even more motivation for the coming season. I hope to continue to progress and, as a team, that we make a good start to the season. The preseason camp in Tignes will be a great way to get back to work."
