Tottenham are expected to complete the signing of Sergio Reguilon, according to reports.
Manchester United had been in pole position to sign the left-back from Real Madrid.
But Real's insistence on a buy-back clause has put United off the deal.
And BBC says Spurs have swooped in to bring the 23-year-old to north London.
Daniel Levy is also in negotiations with Real over a loan deal for Gareth Bale, who was also a target for United.
