Tottenham have completed the signing of defender Federico Fazio from Sevilla.
Spurs announced the sale of centre-back Michael Dawson to Hull City on Tuesday and they have wasted no time in bringing in a replacement.
ESPN FC reported on Tuesday that the deal was imminent and, according to reports, Tottenham were willing to pay Sevilla's eight million-pound release clause to sign Fazio, who has penned a contract until 2018.
"I'm really happy to be here at this club, this great club with very good players. I'm really happy to be here," Fazio told Tottenham's official Twitter account.
"I came to Tottenham because I think it's a very good team, a very good club with very good fans."
The 27-year-old joined Sevilla in 2007 from Argentine side Ferro Carril Oeste and went on to win the Copa del Rey and the Europa League with the club.
Fazio, who has gained two caps for Argentina, was part his nation's under-20 World Cup-winning side in 2007, while he also won Olympic gold in 2008.
