Brugge value Nusa at £25million and want to loan the Norwegian back for the rest of the season.
The 18-year-old has banged in four goals in 43 Belgian Pro League appearances after bursting onto the scene in the 2021/22 campaign.
Nusa became the youngest player in Champions League history to score on his debut during a 4-0 win over Porto in September 2022.
The winger has already won four caps at senior international level for Norway.
Should Spurs wrap up a deal to sign the forward, he will be the club's third transfer of the winter window.
