Nottingham Forest are determined to keep full-back Neco Williams this summer amid late interest from Tottenham.
Spurs' interest in the 25-year-old is at an exploratory stage, but sources close to Forest insist the City Ground club will not consider selling the Wales international this summer.
Williams proved a crucial player last season and is expected to play a key role for new manager Oliver Glasner this time around. Forest remain in talks with the former Liverpool defender over a new contract and it is their intention to extend his current deal - which expires in summer 2929 - to reflect his importance to the squad.
Reds boss Glasner has an interest in Tottenham midfielder Lucas Bergvall, which poses a potential discussion point between the two clubs, but Spurs manager Roberto de Zerbi has insisted the 20-year-old Sweden international will stay in north London.
Tottenham have sold defender Djed Spence to Inter Milan and are open to signing a replacement - and it is understood De Zerbi would prefer one with Premier League experience.
Like Spence, Williams - who has made over 150 Premier League appearances - can play on both flanks, but is predominantly a left-back.
Spurs have options on the left in Destiny Udogie, Any Robertson and Ben Davies. Udogie is understood to have interest from Italy, while Robertson and Davies are in the latter stages of their careers.
At right-back, Pedro Porro is first choice but there is no direct competition - though Archie Gray can fill in.
As a result, there is a will at Spurs to sign a younger, versatile full-back before the window closes at 23:00 BST on 1 September.
