France midfielder Moussa Sissoko has signed for Tottenham on a five-year contract from Newcastle.
The 27-year-old was the subject of a late move from Spurs, who beat Everton to signing the midfielder for a reported £30million fee.
"Very happy to join @SpursOfficial for the next 5 years!," Sissoko wrote on Twitter.
With just a few hours to go before the close of the window the Toffees believed they were in pole position to secure the Newcastle midfielder having met his £30million asking price - something Tottenham were apparently unwilling to do.
However, despite striking a deal with the club Everton failed to agree personal terms and it is understood they had difficulty getting the 27-year-old and his representatives to the negotiating table.
That delay gave Spurs enough time to re-enter the race, match Everton's bid and get the France international to agree a five-year deal just minutes before the deadline.
Tottenham and Newcastle confirmed the deal, and a statement from Spurs read: "We are delighted to announce the signing of Moussa Sissoko from Newcastle United."
"The powerful midfielder made the move to the Premier League with the Magpies in January 2013, representing them on 133 occasions and scoring 12 times.
"He began his career in France with Toulouse where he established himself as a key figure during 219 appearances for the Ligue 1 club, scoring 23 goals.
"Having represented France at every level from Under-16 to Under-21, he made his senior international debut for Les Bleus in 2009 in a World Cup qualifying win over Faroe Islands and has gone on to claim 44 caps in total, including being a member of the team that reached this summer’s Euro 2016 Final."
