<human>: Ronaldo de Assis Moreira (born 21 March 1980), commonly known as Ronaldinho (Brazilian Portuguese: [Ronaw'dZinu]) or Ronaldinho Gaucho, is a Brazilian former professional footballer and ambassador for Spanish club Barcelona. He played mostly as an attacking midfielder, but was also deployed as a forward or a winger. He played the bulk of his career at European clubs Paris Saint-Germain, Barcelona and Milan as well as playing for the Brazilian national team. Often considered one of the best players of his generation and regarded by many as one of the greatest of all time, Ronaldinho won two FIFA World Player of the Year awards and a Ballon d'Or.

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 Clasico. 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 Bernabeu 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."  The season is considered one of the best in Ronaldinho's career as he was an instrumental part of Barcelona's first Champions League title in 14 years. After winning their group convincingly, Barcelona faced Chelsea in the round of 16 for a rematch of the previous year. Ronaldinho scored a decisive goal in the second leg, going past three Chelsea defenders on the edge of the penalty area before beating the goalkeeper, sealing Barcelona's qualification to the next round. He also contributed one goal in Barcelona's elimination of Benfica in the quarter-finals with a 2-0 home victory. After a 1-0 semifinal aggregate win over Milan, in which Ronaldinho assisted the series' only goal by Ludovic Giuly, Barcelona progressed to the Champions League final, which they won on 17 May 2006 with a 2-1 defeat of Arsenal. Two weeks earlier, Barcelona had clinched their second-straight La Liga title with a 1-0 win over Celta de Vigo, giving Ronaldinho his first career double.  Ronaldinho finished the season with a career-best 26 goals, including seven in the Champions League, and was chosen for the UEFA Team of the Year for the third consecutive time and was named the 2005-06 UEFA Club Footballer of the Year. He was named in the six man shortlist for the 2006 Laureus World Sportsman of the Year, and was selected in the FIFA World XI. CANNOTANSWER
