The 23-year-old left-back was keen on a move to Manchester United, but the Premier League giants failed to agree on a deal with Real Madrid.
The Red Devils refused to agree to Real Madrid’s insistence on including a buy-back and a first refusal clause as they wanted to sign Reguilon for the long term.
Tottenham swopped in and managed to agree on a fee while agreeing to let Real Madrid include the clauses that could see Reguilon move back to the Santiago Bernabeu in the future.
Real Madrid were keen on the buy-back clause and, according to Spanish daily Marca, the player’s representatives also wanted the clause including.
Reguilon does not want to close the door on returning to Real Madrid and believes he has the ability to play for the club in the future.
The Spaniard will soon travel to England to complete the move to Tottenham and already has an agreement in place over a contract.
The deal could be completed as soon as Thursday, as Jose Mourinho moves closer to capturing the defender.
The buy-back clause will be set at between €35m and €40m.
