When Zidane's majestic strike flashed into the net to give Madrid victory in the 2002 Champions League final against Bayer Leverkusen, the French star must have believed he would never surpass that golden moment in Europe's top-tier tournament.
Yet at Cardiff's Principality Stadium on Saturday, he joined the managerial immortals as Madrid's 4-1 rout of Juventus made him the first coach to win successive European Cups since the great Arrigo Sacchi of AC Milan in 1989 and 1990.

Not even Alex Ferguson, Jose Mourinho or Pep Guardiola have achieved that epic feat.
"All the coaches you mentioned, they're great coaches. I don't want to say I'm very good because before I was scandalously bad and now I'm supposed to be the best," Zidane said modestly. "I have the chance to be with this great squad. In the long run, everyone's been very important. For me that's the success."
Madrid's impressive win rightly sparked praise for Cristiano Ronaldo's predatory brace.
But it was Zidane who provided the inspiration for Madrid's first La Liga and Champions League double since 1958.
After taking the lead through Ronaldo, Madrid were rocked back on their heels by Mario Mandzukic's stunning overhead kick equaliser before the interval.

However, Zidane turned the tide in the space of a few words when he faced his uncertain players in the dressing room.
Imploring his stars to believe in themselves as much as he did in them, Zidane struck the right tone and eased their fears that the trophy may slip from their grasp.
Ronaldo admitted it was in those moments that the match was won.
"Zidane gave us a very positive half-time team talk and told us he really believed in us," he said.
With Zidane's words ringing in their ears, Madrid were revitalised in the second half, scoring three times to seal the famous 'cup with the big ears'.
As he stood on the pitch amid the confetti and fireworks at full-time, a bashful smile across his face, Zidane could have been forgiven for letting his mind drift back to his childhood.
Born among Marseille's toughest streets, Zidane said this week: "If you said I was going to live all of this when I was a child quite frankly I would never have believed, but here I am living it."
Throughout an incredible playing career that brought him fame and fortune, Zidane remained a reluctant hero, even when he became the idol of a nation by starring in France's 1998 World Cup triumph.
But it was that calm demeanour that appealed to Madrid chief Florentino Perez when he made the surprise decision to appoint Zidane as boss in January 2016.
With only brief spells as Madrid's assistant coach and 'B' team boss on his CV, critics wondered how he would cope with a squad of fragile egos at a club rife with political power struggles.
Those doubters underestimated Zidane's inner resolve and the huge respect he was held in by Madrid's players.
Here was a manager who could match them medal for medal and they quickly responded to his leadership.
A Champions League final victory over Atletico Madrid last season might have been seen in some quarters as beginner's luck.
But Zidane had all the right answers this season.
Aware that Ronaldo had been below his best in two Champions League finals after feeling overworked earlier in those campaigns, he rested the forward nine times this season and was rewarded with 16 goals in his last 10 appearances.
Even the difficult decision of whether to recall Wales forward Gareth Bale for the final in his hometown was no problem for Zidane, who kept faith with Isco and watched his playmaker pull the strings impressively.
Blessed with the Midas touch, Zidane's success is no fluke and there's no end in sight.
