The Juventus stadium broke into applause and Real Madrid coach Zinedine Zidane, once a player of extraordinary gifts himself, looked dumbstruck at the audacity of Cristiano Ronaldos goal. Just when everyone thought the Portuguese had done it all, he produced a strike in Reals 3-0 Champions League quarter-final, first leg win at Juve on Tuesday that was astonishing even by the standards of his remarkable career. Real were 1-0 ahead and struggling to keep the hosts at bay when Ronaldo, with his back to goal, launched himself into the air to meet Dani Carvajals chipped cross with a bicycle kick — known in Spanish-speaking countries as a Chilean — that flew past dumbfounded Juventus goalkeeper Gianluigi Buffon. The timing was perfect while the athleticism, worthy of a youngster more than than a 33-year-old, ridiculed suggestions that the record-amassing Portugal forward is past his prime.
