Bocaly made his debut on 5 March 2006 against rivals Paris Saint-Germain in the annual "Classique" under bizarre circumstances. In protest against security flaws at the Parc des Princes, Marseille president Pape Diouf decided to use players from the club's youth academy and CFA2 reserve team in the match. Despite media expectations of heavy defeat, the youngsters held PSG to a goalless draw. Bocaly played the whole match, and fansite "OMplanète" thought him the player most likely to make a breakthrough. In April, he signed his first professional contract, of three years.
