Kylian Mbappé finally put on a Real Madrid jersey on Tuesday, fulfilling his childhood dream in front of a packed Santiago Bernabeu Stadium.

Nearly 80,000 fans were in hand at the Bernabeu to welcome the 25-year-old France star during his official presentation as the club's newest player.

After signing his five-year contract with the Spanish powerhouse alongside club president Florentino Pérez, Mbappé entered the stage set up at the Bernabeu to loud cheers by the Madrid fans.

Wearing the No. 9 jersey, Mbappé smiled broadly and waved to the fans who chanted his name, then embraced Pérez and former Madrid player and coach Zinedine Zidane, who invited Mbappé to visit the Spanish club for the first time when he was just a teenager.

“It's an incredible day for me," Mbappé told the crowd, in good Spanish. ”Since being a kid I dreamed about playing for Madrid and today I'm here. It means a lot to me."

Mbappé finished his speech by asking the crowd to join him and chant “Hala Madrid,” similar to what his childhood idol – and “now friend” – Cristiano Ronaldo did when he arrived at the club. Mbappé then kissed the club’s shield and went around the Bernabeu kicking balls to the crowd in the stands.

“Now I have another dream, which is to live up to the history of this club, the best club in the world,” he said. “I’ll give my life to this club and to this shield.”

The record 15 European Cups won by Madrid were on display on the stage where Mbappé was introduced. His relatives, club officials and several former players were also by the stage.

“I see my family happy, I see my mother crying,” said Mbappé, who earlier Tuesday underwent his physical with Madrid's doctors.

The message “Welcome, Mbappé” was shown on the large video boards at the newly revamped Bernabeu, which had its roof closed for the midday ceremony in the Spanish capital. (AP)
