Eric Dier has signed a new five-year deal at Tottenham that will keep him at the club until 2021.
Dier joined Spurs from Sporting Lisbon for £4m ahead of the 2014-15 season and made a dream start, scoring the winning goal on his debut in a 1-0 victory against West Ham on the opening day of the campaign.
The 22-year-old has played 87 times in total for Tottenham and scored six goals, having moved from a defender to a holding midfielder during his time at White Hart Lane.
His performances for Spurs have earned him international recognition and he has already won 11 caps, the last of which came in Sam Allardyce's first game as England boss, the 1-0 win in Slovakia on September 4.
Dier has played in all four Premier League matches for Mauricio Pochettino's side this season, including the 4-0 win at Stoke on Saturday.
"The manager has been great for me since I've been here and all the young players coming through," said Dier. "I have a very good relationship with all the players here.
"We're a good group and we're ambitious and looking forward. The new training ground is on its way so I think it is a fantastic time for the club.
"We are very excited to play Champions League football as it's the highest level of club football and for it to be at Wembley means it will be very special and hopefully we can create some special memories for Tottenham.
"Quite a few players have played there before in international matches and we played there before in the Capital One Cup final. We have trained there now so everyone is used to the surroundings there and everyone is very excited."
