Tottenham have made a bid worth £25.73m (€30m) for Barcelona right-back Emerson Royal.
If Barcelona opt to accept the bid, personal terms for the player are not expected to be a problem.
Tottenham boss Nuno Espirito Santo is hoping to bolster his defensive options, having played Japhet Tanganga at right-back in the opening Premier League games with Serge Aurier now out of favour at the club.
Brazilian Emerson joined Barcelona in 2019 from Atletico Mineiro. He then moved to Real Betis, but returned to the Nou Camp this summer when Barcelona exercised a buy-back clause.
The 22-year-old was a regular under Manuel Pellegrini and helped Betis reach the Europa League last season.
