Consequently, there are now fears that Pochettino will be become disillusioned with life at Tottenham if he isn’t given increased funds this summer.
If chairman Daniel Levy has any aspirations of keeping Pochettino at the club, then he will certainly need to back him in the transfer window.
So we’ve picked out seven players that Spurs could target to keep Pochettino happy.
Matthijs de Ligt – Ajax
It makes sense, then, that Tottenham are reportedly interested in him, considering they may be about to lose Alderweireld, one of the best defenders in the country.
The teenager has previously been linked with Barcelona and Arsenal, as Ajax value him at around £50m.
Key stat: De Ligt became the youngest player to feature for the Netherlands (17y 225d) after making his debut for the national side in March.
Kalidou Koulibaly – Napoli
Last week, Pochettino spoke of beginning a “new project” at Tottenham, which could suggest that he wants to focus on the short-term rather than continuing to build for the future.
The Napoli centre-back has been an established name in Serie A for some time and was part of the joint-second best defence in the Italian top-flight this term.
Chelsea and Arsenal are reportedly set to lock horns in an effort to lure Koulibaly to the Premier League this summer, but Spurs may attempt to entice the Senegal international with Champions League football.
Key stat: Koulibaly has been more accurate with his passing than any other Napoli player in Serie A this season (91%).
Mateo Kovacic – Real Madrid
Modric’s influence has waned ever so slightly this season, but there is still a good chance he will hold down his place in Madrid’s line-up next term.
Mousa Dembele is expected to leave Spurs this summer, and Pochettino will require a top class central midfielder to replace the Belgian.
According to AS, the 22-year-old is on Tottenham’s shortlist, and he could have a big decision to make this summer with a number of Serie A clubs also thought to be keen.
Layvin Kurzawa – Paris Saint-Germain
Ben Davies has done a fine job at left-back this season, but Spurs have lacked the dynamism of a fully fit Danny Rose.
Although he isn’t really considered a first-choice player anymore, Rose will need replacing with a new attacking full-back this summer.
Kurzawa has been rotated with the more defence-minded Yuri Berchiche, who incidentally is a former Tottenham player.
Key stat: Back in October, Kurzawa scored three times against Anderlecht, becoming the first defender to score a hat-trick in the history of the Champions League.
Ryan Sessegnon – Fulham
According to the London Evening Standard, Fulham are determined to hold onto teenage sensation Ryan Sessegnon for at least a year if they are promoted to the Premier League.
But Sessegnon, who scored his 16th goal of the season to book Fulham’s place in the play-off final, just keeps increasing his own chances of earning a move to one of the ‘Big Six’ clubs.
He would provide a useful wide option in attack as well as possibly filling in at wing-back – in fact, Tottenham may not need a Rose replacement if Sesesgnon arrives.
Key stat: With 16 goals and seven assists, Ryan Sessegnon has been directly involved in more Championship goals (23) than any other Fulham player this season.
Riyad Mahrez – Leicester City
Had Riyad Mahrez failed to light up the Premier League in Leicester’s 2015-16 title-winning campaign, then we might be talking about Tottenham as previous champions of England.
Inevitably, Tottenham have been linked with the Algerian a few times since then, and the Standard claimed Spurs were monitoring his situation last summer.
Manchester City came close to signing Mahrez in January, but there is a chance the champions will pursue other targets this summer, giving Tottenham an opportunity to pounce.
Key stat: Mahrez has been involved in 39% of Leicester’s 56 Premier League goals this season. Only four players have been involved in a higher percentage of their teams’ goals – Salah, Gross, Kane and Shaqiri. (Via @OptaJoe.)
Nabil Fekir – Lyon
If Mahrez proves too difficult to lure, Lyon star Nabil Fekir could be an interesting alternative.
Tottenham have struggled to find an able deputy for Harry Kane over the last couple of years – Fekir could solve that problem.
Key stat: Fekir has been on target with 68% of his shots in Ligue 1 this season, a better accuracy rate than Neymar (63%).
