Which association football club was recognized as the FIFA Club of the 20th Century?

Real Madrid Club de Fútbol, commonly referred to as Real Madrid, is a Spanish professional football club based in Madrid. Founded on 6 March 1902 as Madrid Football Club, the club has traditionally worn a white home kit since inception. The honorific title real is Spanish for "royal" and was bestowed to the club by King Alfonso XIII in 1920 together with the royal crown in the emblem. Unlike most European sporting entities, Real Madrid's members have owned and operated the club throughout its history.

Real Madrid established itself as a major force in both Spanish and European football during the 1950s, winning five consecutive European Cups and reaching the final seven times. This success was replicated in the league, which the club won five times in the space of seven years. This team, which included Alfredo Di Stéfano, Ferenc Puskás, Francisco Gento, and Raymond Kopa, is considered by some in the sport to be the greatest team of all time.

Real Madrid was recognised as the FIFA (Fédération Internationale de Football Association) Club of the 20th Century on 11 December 2000. The club was also awarded Best European Club of the 20th Century by the IFFHS (International Federation of Football History & Statistics) on 11 May 2010.
