The Sports and Economics Law Center based in Limoges (France) plays a key role a in the professionalization of sport in France. It’s also an international renowned university laboratory which trains experts in major team sports like Zinedine Zidane in 2012 -2013, former players, managers and coaches.

Among these former high-level athletes in reconversion, Fred Weis, former player of Limoges CSP, Olympic Vice Champion of basketball and Champion of Europe, will distinguish himself differently this time and not only for sport related reasons.
