Radu Dragusin is officially a Tottenham player.
Spurs have announced the 21-year-old's signing from Genoa for £25.8million, £4.3m of which will be paid when certain add-ons are triggered.
Djed Spence's loan move to the Italian club has been also confirmed as part of the deal.
The announcement draws to a close a saga of-sorts to open the January transfer window after the two clubs haggled over a fee, amid interest from Napoli and AC Milan.
Bayern Munich swooped in with a late offer, outbidding the personal terms on offer at Tottenham, but the player's desire to move to the Premier League helped see Spurs' move through.
Dragusin has put pen to paper on a contract to 2029 after flying in for his medical on Wednesday.
Spurs hope to hand the Romanian defender his debut in this weekend's trip to Manchester United amid injury concerns over Micky van de Ven - who could be pronounced fit - and Cristian Romero.
Timo Werner, the capital club's other signing of the window so far, is also set to be involved in the squad.
