London - Tottenham signed Southampton goalkeeper Paulo Gazzaniga for a reported £2 million on Wednesday.
Gazzaniga agreed a five-year contract and will compete with Michel Vorm to fill the role as the main understudy to Tottenham's first-choice keeper Hugo Lloris.
The 25-year-old Argentine, who spent last season on loan at Spanish club Rayo Vallecano, started his career at Valencia before moving to England with Gillingham in July 2011.
"I feel amazing and am so happy to start training with the boys," Gazzaniga said.
"This is an amazing club and the facilities are unbelievable."
Gazzaniga is Tottenham manager Mauricio Pochettino's second signing since the end of last season, following the arrival of Ajax defender Davinson Sanchez for a reported club record £42 million.
Pochettino had previously worked with Gazzaniga during his spell in charge at Southampton.
Gazzaniga, though, knows he will face a battle to force his way into the first-team squad ahead of Tottenham captain Lloris and experienced Dutchman Vorm.
"I can learn a lot from them, because they are world-class goalies," he said.
"I think Hugo will be a good teacher for me, I like to watch them and try to improve myself and think I am in the right place to do that."
