White hot: Dembele is one of four Belgian stars at White Hart Lane

By Tottenham correspondent Tony Hughes

Mousa Dembele has signed a new Tottenham contract in a major boot to the Premier League title contenders, Football Insider sources understand.

The 28-year-old has reached an agreement on an extension to his current deal, which ends in the summer of 2017.

Dembele has been in talks with the club for months about a new contract 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.
