Theo Hernandez said he was ‘very happy to be at the best club in the world’ after being unveiled as Real Madrid’s first summer signing.
The 19-year-old defender joined from city rivals Atletico in a £20million deal after Real triggered a release clause in his contract.
The Frenchman had not played for Diego Simeone’s side but impressed during a loan spell at Alaves last season.
He said: ‘Thank you so much to the fans and players for this reception.
‘I am very happy to be at the best club in the world and I have come here to learn from the best players and to win titles.
Hernandez was unveiled as a Real Madrid player at a ceremony which began with the screening of a video featuring his career highlights.
Pérez said: ‘Congratulations because you’re now a Real Madrid player and that owes to your talent and personality and all that you’ve shown despite your young years’.
‘First and foremost, you wanted to come here and defend this badge despite other big European clubs wanting to sign you. Your commitment and conviction is something that won’t be forgotten by everyone at Real Madrid.
‘You were one of the breakthrough stars of last season’s La Liga campaign and you’ve proved that you’ve got enough potential, quality, ambition, strength and determination to play for Real Madrid’.
‘These supporters will always be behind you because we’re aware of your ability to fight in every game and just how keen you are to win. You’re joining a club that has won 12 European Cups and you become a part of the history of the biggest club in the game. I know that you’ll give your all for this badge and for your family.’
The 19-year-old, who spent last season on loan at Alaves, never made a senior appearance for Diego Simeone’s side.
He featured in two pre-season matches last season and was under contract until 2021. But both Atletico and Real have now confirmed that Hernandez will cross the city divide to join Los Blancos.
The defender, who was born in the French city of Marseille, joined Atletico in 2008 at the age of 11 before rising up the ranks of their youth system.
