Tottenham have signed Toby Alderweireld for an undisclosed fee from Atletico Madrid on a five-year contract.

"Looking forward to this but also looking back at a great Southampton season. Great club and fans," the 26-year-old Belgium defender said.

He has 47 caps for Belgium and joins international team-mates Nacer Chadli, Mousa Dembele and Jan Vertonghen at White Hart Lane.

"It's a big club and it's always been a dream to play at a club like Spurs," he told Tottenham's website.

"Now that dream is coming true so I'm very happy, very proud and I will give my best."
