Kuffour was also part of the Bayern team which lost to Manchester United due to two late goals in the 1999 UEFA Champions League Final, famously beating the ground in frustration afterwards, a gesture that endeared him to Bayern supporters. He also became the youngest defender of all-time to score in the Champions League, at the age of 18 years, 61 days during the match against FC Spartak Moscow on 2 November 1994, which ended in a 2–2 draw. Kuffour made over 60 UEFA Champions League appearances, being one of the most decorated African players of all time.
