Eric Dier has agreed a new five-year deal at Tottenham – and the club’s supporters have revealed their delight on Twitter.

The England midfielder has signed a contract which keeps him at White Hart Lane until 2021 after becoming a crucial player under Mauricio Pochettino.

Football Insider revealed last weekend that the defender-turned-midfielder had agreed the terms of a deal worth £19.5million.

Dier, 22, has developed into one of Spurs’ most reliable players and was a crucial member of the side that finished third last season.

The defensive midfielder struck up a formidable partnership with Mousa Dembele last season and has continued to do so with new signing Victor Wanyama at the beginning of this campaign.

Spurs supporters have posted on Twitter their excitement that Dier has committed his long-term future to the club and several have even labelled him as a future captain.

Here are a selection of their messages:

Dier joined Spurs from Portuguese side Sporting in 2014 and has already made 91 appearances for the club, scoring six goals and supplying four assists.

He has also become a regular for the England national team and was one of the better players in a disappointing Euro 2016.

Pochettino has built his exciting Spurs side around a young English core of talents and Dier has linked well with team-mates Dele Alli and Harry Kane in particular.

Spurs will now turn their attention to their Champions League group match against Monaco on Wednesday, which will be played at the national stadium Wembley.
