Mousa Dembele has signed a new Tottenham contract worth £12.7million, Football Insider sources understand.

Spurs announced on Friday that the midfielder has finalised a contract extension with the club he joined in the summer of 2012.

His new deal lifts his salary from £40,000-a-week to £70,000-a-week and runs until 2019, replacing his current agreement, which was due to expire in the summer of 2017.

Football Insider revealed in November that Dembele was ready to commit to a new contract after opening fresh talks.

Dembele had been in talks with the club for months about a new deal after establishing himself as a key player under Mauricio Pochettino this season.

The midfielder had been facing an uncertain future at the start of the campaign after falling behind Nabil Bentaleb, Eric Dier and Ryan Mason in the pecking order for central places but he has played some of his best football for two seasons since returning to the team in October.

The Belgium international, who has won 61 caps for his country, scored three goals in consecutive matches and has maintained that form for Pochettino’s rejuvenated side.

Dembele has already made 16 Premier League starts this term, compared to the 10 games he started in the entirety of last season.

The versatile midfielder has mostly been used as Dier’s central partner, although he has also been deployed in a more attacking role at times.
