Willy David Frédéric Sagnol is a French former professional footballer who played as a defender.
Sagnol spent much of his professional career playing for Bayern Munich in Germany's Bundesliga. He was also part of the French squad at the 1997 FIFA World Youth Championship, 2002 FIFA World Cup, UEFA Euro 2004, 2006 FIFA World Cup and UEFA Euro 2008.
Sagnol was part of France's squad for the 2006 FIFA World Cup in Germany, starting each of his country's seven games en route to the final. His competent performances, aided by France's progression to the final led to him being named as one of the outstanding defensive performers in the tournament. He saved his best display for the biggest stage of them all, the World Cup final, and was one of the better performers in a game largely remembered for off-the-ball events rather than on-the-field performances. Indeed, Sagnol's name could have been immortalised had his strong effort on goal not been successfully repelled by Gianluigi Buffon. Nonetheless, his performance was notable for a solid defensive contribution as well as important involvement in several attacking moves, such as when he provided a cross for his captain Zinedine Zidane, whose header was again superbly saved by Buffon. Sagnol also took the final spot kick for France in the 2006 FIFA World Cup.
