Example Input: Question: Who did Eintracht Frankfurt defeat in the 1959 German Championship? Passage:His club was Eintracht Frankfurt with whom he won the 1959 German Championship, and in 1960 reached the finals of Champion's Cup against Real Madrid. The left-footed Don Alfredo was the head of the team. Pfaff was a true playmaker with exceptionally good ball control and great skills at free kicks. Pfaff probably would have accumulated more than seven caps if Fritz Walter had not played the same role for West Germany as Pfaff played for Eintracht Frankfurt. In 1954, Atlético Madrid offered him 180,000 D-Mark but his wife Edith was against a move to Spain. Possibly Pfaff's greatest game was the 6–1 against Rangers F.C. in the 1959–60 semifinal first leg of the European Champion Clubs' Cup, which was followed by a 6–3 win of Eintracht Frankfurt in Glasgow in the second leg. He ended his career in 1962 at the age of 36.
