Sergio Reguilon is at Tottenham's training ground as the Real Madrid defender closes in on a move to the club.
The left-back arrived at Hotspur Way on Wednesday ahead of completing a medical on Thursday, with official confirmation likely coming before Spurs take the field in Bulgaria to face Lokomotiv Plovdiv in the Europa League in the evening.
Reguilon is expected to cost around £25million, with Tottenham agreeing to include a number of clauses in the deal.
Real Madrid will have the option to buy back the 23-year-old for around £36m within two years and meet any fee Spurs agree with another club.
Should the deal be finalised on Thursday, the club will be able to register Reguilon in time for Sunday's trip to Southampton.
