Transfer talk: July 5 - Spurs get Sigurdsson, Mascara to Al Nasr
The Iceland midfielder has signed a reported five-year deal at White Hart Lane following his impressive loan spell at Swansea last season.
He had also been linked with a permanent move to the Welsh side after they agreed a club record £6.8m (Dh39m) with Hoffenheim.
But Sigurdsson opted to move to White Hart Lane after a meeting with the Spurs' hierarchy, who persuaded him the north London club are destined for great things.
"I enjoyed playing under Brendan and I am grateful for everything he has done for me, but after careful consideration I liked Spurs best," he said.
"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.
The midfielder has already spoken to Andre Villas-Boas, who was named as Harry Redknapp's replacement, and is looking forward to working under the Portuguese.
"I like him and the ideas he has," Sigurdsson added.
Sigurdsson's arrival has raised questions about the future of Luka Modric.
The Spurs playmaker, who last year was the subject of a £40 million bid from Chelsea, has made it clear he wants to leave White Hart Lane, and Sigurdsson is being viewed by some as a like-for-like replacement.
Italian playmaker Giuseppe Mascara looks set to move to the Pro League after confirming he is to link up with Al Nasr.
The 32-year-old had previously undergone a medical with the club, but had not signed a deal.
But Mascara's deal now looks to have been concluded, with the player telling a Napoli radio station he was leaving Novara to move to the Pro League.
“I had wanted to stay with Novara, but the club told me that if there was an important offer then I could evaluate it and eventually the one from Al Nasr seemed like the best possible," he said.
“In Dubai there are many great characters. Diego Maradona? To meet him would be the dream of my life.”
The 34-year-old World Cup winner penned a two-year contract with the Serie A champions today after completing a medical.
"The Brazilian defender joins the Bianconeri on a free transfer and has signed a two-year contract, keeping him with the club until 30 June 2014.," a statement on Juve's official website read.
Lucio had established himself as one of the best defenders in Italy since his arrival at San Siro, from Bayern Munich, in 2009.
He immediately helped Inter, then under the stewardship of Jose Mourinho, to the scudetto and Champions League titles in his first season.
Scottish champions Celtic have confirmed the signing of on-loan goalkeeper Fraser Forster to a permanent deal.
The 24-year-old had spent the last two seasons on loan at Parkhead from Newcastle United.
