Tottenham have completed the transfer of Bongani Khumalo from South African side Supersport United on a four-and-a-half year deal.
Khumalo impressed during a trial at Spurs last July and the north London club have chosen to take the 23-year-old on a permanent transfer for a fee of around £1.5million.
The centre-half, who was born in Swaziland, impressed for South Africa during the World Cup where he scored the opener in the hosts' 2-1 group stage win over France.
Spurs boss Harry Redknapp already has a number of options in defence but there are still doubts over the long-term fitness of centre backs Ledley King and Jonathan Woodgate.
Khumalo could make his debut in Tottenham's FA Cup third round clash with Charlton at White Hart Lane on Sunday.
