Zidane's side beat Atleti at the final Madrid derby at the Vincente Calledron before Diego Simeone's team leave their historic home at the end of the season.
Zinedine Zidane is convinced Cristiano Ronaldo's hat-trick in the derby triumph over Atletico Madrid has closed the 2016 Ballon d'Or debate.
The former Manchester United winger Ronaldo bagged three goals, one in the first half and two in the second, as Los Blancos sealed a win in the final Spanish capital derby at the Vicente Calderon.
However, following the triumph that puts them four points clear at the top of the table, Zidane said Ronaldo - who became the leading goalscorer in the history of the Madrid derby - should win his fourth Ballon d'Or on January 11.
"I've never had doubts that Cristiano is the best and tonight closes the debate," he said as Omnisport reported.
Zidane, who won the Ballon d'Or in 1998, said the win over their bitter rivals on Saturday is the highlight of his brief career as a coach.
"I do not know if [it is] the best, but we played a huge game against a difficult opponent and in a stadium where it is difficult to win," the Frenchman said.
"In the second half it was logical Atletico's pressure [increased] in those first 15 minutes, but we produced the necessary intensity against a complicated opponent.
"It is an important victory for us, on a difficult pitch and with a rival that gives you a war. We played a very good game from the beginning. There are not many teams that can win on this pitch and we did well."
When asked if he will miss the Calderon when Atletico move to their new ground for the 2017-18 campaign, he replied: "Yes, sure. The players, fans... they are going to miss it. We're happy about this victory because there are not many teams that win here."
