In an Instagram post, the French midfielder spoke out on the ruling shortly after it was made, criticising it as "incorrect" and vowing to appeal. He wrote: "I have today been informed of the Tribunale Nazionale Antidoping’s decision and believe that the verdict is incorrect. I am sad, shocked and heartbroken that everything I have built in my professional playing career has been taken away from me. When I am free of legal restrictions the full story will become clear, but I have never knowingly or deliberately taken any supplements that violate anti-doping regulations.
"As a professional athlete, I would never do anything to enhance my performance by using banned substances and have never disrespected or cheated fellow athletes and supporters of any of the teams I have played for, or against. As a consequence of the decision announced today, I will appeal this before the Court of Arbitration for Sport."
