Spurs have already paid the Championship side £9m for teenage winger Jack Clarke, who will remain at Elland Road on loan next season.
And now, the Mirror claims that Spurs will attempt to buy another Leeds player this summer.
Phillips is a boyhood Leeds United fans and the club are confident he will not agitate for a move away this summer, although Spurs can offer him Champions League football and a significant increase on his £10,000-a-week wages.
Spurs are not the only club interested in Phillips. Aston Villa were the first to express an interest in the rising star, offering £11m, which Leeds rejected.
Newcastle United, Bournemouth and Wolves have also scouted the midfielder.
Elsewhere, Spurs are reportedly interested in signing Real Madrid forward Mariano Diaz to bolster their attacking options this summer.
Spanish newspaper AS has claimed that Spurs have joined Roma and AC Milan in the race for the 25-year-old Dominican Republic international, who re-joined Real Madrid from Lyon in 2018.
Mauricio Pochettino reportedly sees Diaz as the perfect replacement for Fernando Llorente in his matchday squad.
However, AS claims that the player is unsure over a move to north London because he knows he will spend much of his time playing second fiddle to Harry Kane.
The striker is desperate for regular first-team football, having made just 19 appearances for Madrid last season, scoring four goals.
Sky Italia have claimed that Roma are planning on recruiting two defenders this season. One is Gianluca Mancini from Atalanta. And the other will be either Marc Bartra of Real Betis or Toby Alderweireld.
Spurs have yet to receive an offer for the Belgium international but have made it known that he is available this summer for £25m.
As things currently stand, Alderweireld is still expected to join his Tottenham team-mates for their pre-season tour of Asia.
Meanwhile, Diaz is not the only Real Madrid player Tottenham have designs on, as it has been reported by some outlets that the club have finally agreed a deal for Dani Ceballos.
Spurs have already shattered their all-time transfer record by signing Tanguy Ndombele from Lyon for £55m this summer, but Mauricio Pochettino is determined to recruit at least one more midfielder as he overhauls his ageing squad.
And, according to reports in Spain, that man could be Ceballos with an agreement now close.
The 22-year-old shone for Spain at the European Under-21 Championship in Italy and with Real Madrid looking to shift some of their fringe players could be available for a figure in the region of £44m.
However, talks over Real Betis midfielder Giovani Lo Celso have stalled, according to Sky Sports News.
The 23-year-old Argentina international is one of Pochettino’s top targets this summer and is seen as a ready-made replacement for Christian Eriksen, should the Dane depart for the bright lights of Real Madrid.
But Betis are holding firm over their £70m valuation of Lo Celso, who last season scored 16 goals and registered six assistant in 46 matches for the club.
That’s more than Tottenham are currently prepared to spend, with the club needed to sell some deadwood before they can finance another huge move.
