Having successfully established themselves as a top four side under the leadership of Mauricio Pochettino, Tottenham will now be asking what the future holds and how far they can go.

The squad has a wealth of top talent and keeping it together has so far been successful. Most players are tied to a long-term contract, but a handful of key individuals are nearing the last year or two of their current deals and some hard choices may have to be made.

Here's a look at exactly when every current Tottenham player's contract expires...

1. Expiring 30th June 2018

Michel Vorm (GK) - Signed his last extension in December 2016 and a decision appears not to have been made about his future. Could pursue opportunities elsewhere as a starter.

No other first team players are out of contract this summer.

2. Expiring 30th June 2019

Toby Alderweireld (DF) - Unlikely to sign a new deal. Spurs have the option of extending of the Belgian's contract by 12 months, but that will bring a £25m release clause into play.

Jan Vertonghen (DF) - Spurs' slightly older Belgian defender has just been named in the PFA Premier League Team of the Year and a new contract is expected in the coming months.

Mousa Dembele (MF) - Linked with a possible move to the Chinese Super League as he nears the final year of his Spurs contract. Would be missed but isn't irreplaceable.

Fernando Llorente (FW) - It wouldn't be a surprise to see him released at the end of the 2018/19 season at the age of 34, if it doesn't happen before then.

3. Expiring 30th June 2020

Kyle Walker-Peters (DF) - Celebrated his 21st birthday earlier this month and next season could be make or break for him at Spurs. A loan might just be a 'shop window' for him.

Cameron Carter-Vickers* (DF) - Has spent the 2017/18 season playing regularly for Ipswich in the Championship. It remains to be seen if there is a place for him back home.

Christian Eriksen (MF) - The Dane has had the season of his life in 2017/18, but with only two more years left on his contract the club is vulnerable unless a new deal is signed.

Erik Lamela (MF) - Has faced exit rumours virtually ever since he arrived in north London nearly five years ago. The winger has overcome serious injury and personal grief.

Son Heung-min (FW) - A top signing who has produced another impressive goal haul this season after netting 22 in 2016/17. A new contract is reportedly in the offing.

Vincent Janssen* (FW) - A fractured ankle ruled the striker out of 19 Turkish league and cup games while on loan at Fenerbahce. It seems clear he has not future at Tottenham.

4. Expiring 30th June 2021

Danny Rose (DF) - Seemingly missing 'the north', it's little coincidence that rumours linking the left-back with other clubs emerged at the same as he was seeking a pay rise from Spurs.

Ben Davies (DF) - Still only 24 years of age, he's been starting left-back for much of the season as a result of Rose's injury woes and remains an important player.

Eric Dier (MF) - Signed a long-term deal at the start of last season and has enjoyed a strong campaign in 2017/18. Arguably one of the Premier League's best holding midfielders.

Victor Wanyama (MF) - Another holding midfielder on a long-term deal. The Kenyan missed much of the first half of the season as a result of a troublesome knee injury.

Moussa Sissoko (MF) - Little more than a fringe player since his £30m arrival from Newcastle in 2016 and has started fewer than half of his Premier League appearances this season.

Georges-Kevin Nkoudou* (MF) - Spurs will need to assess the French winger's future this summer. Has only started two Premier League since joining Bunrley on loan in January.

Josh Onomah* (MF) - A loan with Aston Villa in the Championship has been reasonably successful and it could be that he is loaned out again next season.

5. Expiring 30th June 2022

Hugo Lloris (GK) - The goalkeeper and club captain will have been at Spurs for 10 years if he sees his current contract through to completion. He will also be 35 by the time it expires.

Paulo Gazzanigga (GK) - Joined as third choice goalkeeper from Southampton last summer and could well be promoted to second choice next season depending on Vorm's situation.

Juan Foyth (DF) - One for the future. The centre-back was still a teenager when he arrived from Argentina in August and has been used sparingly up to now to ease him in gently.

Serge Aurier (DF) - The Ivorian's bad boy image looks to have been shed after arriving from PSG last summer, but his clumsiness on the pitch has made a number of Spurs fans turn against him early in his London career.

Kieran Trippier (DF) - Signed a new deal in 2017, two years after joining the club. Now 27 years of age, his current deal will take the right-back to just shy of his 32nd birthday.

Harry Winks (MF) - Injury has disrupted what promised to be a real breakout season for the home-grown midfielder. Still has plenty of time to prove himself once fit again.

Dele Alli (MF) - Has enjoyed a different kind of season in a deeper role in 2017/18 after scoring freely from midfield 12 months ago. Continues to improve and mature.

Harry Kane (FW) - The talisman has already signed several new deals in recent years and one has to expect another will be in the offing before too long to continue warding off suitors.

6. Expiring 30th June 2023

Davinson Sanchez (DF) - Spurs spent a lot of money to buy the Colombian centre-back from Ajax, but it appears to have been a masterstroke and softens Alderweireld's expected exit.

Lucas Moura (MF) - The club's latest signing agreed a five-and-a-half year contract when he arrived from PSG in January. The current expiry will take him beyond his 30th birthday.
