Eden Hazard joined Real Madrid from Chelsea for a fee that could exceed €168m.
The Belgian underwent a medical and then signed his five-year deal alongside Real president Florentino Perez.
Hazard said: ‘My dream ever since I was a child has been to play for Real Madrid’.
After signing his contract, Perez introduced Hazard, who first spoke in Spanish saying: “Hola todos” (hello everyone), before continuing with a short speech in French.
He then changed into the Real kit and walked onto the pitch, before kicking gold and white balls into the crowd and kissing the club’s badge.
Later in a news conference, he said: ‘I’m going to try to become the best player in the world, but first I wanted to be in the best team in the world.’
‘I’m not a Galactico, but I’ll try to be, for now I’m Eden Hazard.’
Hazard did not have a number on his shirt, as the number 10 he wore at Chelsea and for Belgium is taken by Luka Modric at Real.
