Passage: By the end of the year 2005, Ronaldinho had started to accumulate a host of personal awards. He won the inaugural FIFPro World Player of the Year in September 2005, in addition to being included in the 2005 FIFPro World XI, and being named the 2005 European Footballer of the Year. Also that year, Ronaldinho was voted the FIFA World Player of the Year for the second consecutive year. He became only the third player to win the award more than once, after three-time winners Ronaldo and Zinedine Zidane. His domination as the world's best footballer was undisputed as he also won the prestigious Ballon d'Or for the only time in his career.On 19 November, Ronaldinho scored twice as Barcelona defeated Real Madrid 3–0 on the road in the first leg of El Clásico. After he sealed the match with his second goal, Madrid fans paid homage to his performance by applauding, so rare a tribute only Diego Maradona had ever been granted previously as a Barcelona player at the Santiago Bernabéu Stadium. Ronaldinho stated, "I will never forget this because it is very rare for any footballer to be applauded in this way by the opposition fans."
