Arsenal defender Laurent Koscielny is full of praise for former Crystal Palace goalkeeper Steve Mandanda.

The pair are united again with the France squad this week. Mandanda is back after quitting Palace for Marseille.

Koscielny said, "He is a very great goalkeeper. I think that his return to Marseille did him good.

"His year at Crystal Palace showed him that in football nothing is ever guaranteed. He's a golden guy, I like him a lot.

"He is always there to work and give the best for the team."
