The Bordeaux midfielder feels that his side will never have a better opportunity to reach the latter stages of a major tournament, and must take their opportunity now
The co-hosts have been drawn alongside Czech Republic, Russia and Greece in Group A, and the Bordeaux man feels that they have a fantastic opportunity to reach the quarter-finals.
"Our group is not easy," he told FranceFootball. "But it's very open. We'll be frank: if we don't qualify from that group, we'll never qualify.
"We've avoided Germany, Netherlands, Italy and France, and we're playing all of our matches at home. Our chance is here. It's now or never."
