The Icelandic midfielder impressed last term on loan at Swansea, and has been the subject of a transfer wrangle between the Welsh club, Liverpool and Spurs this summer.
Despite this, the talented playmaker has agreed to move to White Hart Lane, and has revealed that a conversation with new club boss Villas Boas swung his decision.
“I like him (Andre Villas-Boas) and the ideas he has,” Sigurdsson told mlb.is, translated to English by Sky Sports.
“He has faith in me and I’m looking forward to working under his leadership.
“I enjoyed playing under Brendan and I am grateful for everything he has done for me, but after careful consideration I liked Spurs best.
“The team has world-class players in their ranks and they play good football, which I like.
“I was impressed with the club’s plans for next season and the coming years. There is clearly great ambition at Tottenham and the club intends to do big things.
“It is a pleasure to see that Gareth Bale has signed a new contract. There are top players in the team and the club is getting a new training ground,” he concluded.
