Former Wolves boss Nuno is unsure about taking the job at Tottenham ahead of talks.
Spurs chief Daniel Levy has turned his attention to Nuno, who is set to leave Wolves upon the expiry of his contract next week.
The Portuguese gaffer is reportedly keen on taking over and will hold talks with Spurs in the near future, despite being previously ruled out of the running.
The Sun says his appointment is by no means a foregone conclusion, as a club source is quoted as saying: "There are still a number of issues".
One of those issues is understood to be over transfers, with Nuno demanding a major say on any dealings behind the scenes.
But that will be a difficult wish for Levy to grant following the appointment of ex-Juventus official Fabio Paratici in June as the club's new sporting director.
Furthermore, Levy is also concerned by Nuno's pragmatic style of play along with his reluctance to give young players first-team football.
