Spurs midfielder Luka Modric has been signed by Real Madrid from Tottenham for a transfer fee of around £30m.
He passed a medical on Monday and has signed a five-year contract with the Spanish team.
"I'm very happy, honoured and proud to be at the biggest and best club in the world. I'm very excited." Modric said.
With less than a week before the current transfer window closes Tottenham are now seeking a replacement for him on the squad.
Spurs boss Andre-Villas Boas has already made three signings this summer, with Emmanuel Adebayor moving from Manchester City for £5 million, midfielder Gylfi Sigurdsson joining from Hoffenheim and Jan Vertonghen signing from Ajax.
