Tottenham Hotspur have signed defender Toby Alderweireld from Atletico Madrid on a five-year contract.
The Belgian defender, who made 26 appearances on loan at Southampton last season, has joined the Whites for an undisclosed fee. The Saints may file a case against Atletico as they had believed they had an option to seal a permanent deal for Alderweireld for £6.8m unless the Madrid club paid £1.5m to buy-back that clause.
“It’s nice when you join another club that you know a couple of players,” the 26-year-old told the official Tottenham website. “From the beginning I knew a lot about it [the club] from Jan Vertonghen, Mousa Dembele and Nacer Chadli.”
“I’m very proud to become a Spurs player,” he added. “I’m very happy to be here and I hope to have a wonderful time with this team.”
The centre-back started his career at Ajax and won three Dutch championships between 2008 and 2013.
He won the Spanish La Liga and reached the final of the Uefa Champions League with Atletico in his first season at the Vicente Calderon, before embarking on a loan move to Southampton.
Alderweireld, who made his senior international debut in 2009, has won 47 caps with Belgium.
