He told L'Equipe: "I learned a lot of things.
"I trained with great players. I learned what the soccer world really is, that it was necessary to be 100% every day, to do always more in the training.
"I wanted to show more, I did not have a chance (with José Mourinho, then Guus Hiddink), but I never gave up. I left for Bremen on January 21, 2016, and I benefited from the Bundesliga by participating in the permanence of the Werder (14 matches)."
