Real Madrid are reportedly considering a reunion with Tottenham Hotspur defender Sergio Reguilon.
The left-back has starred for the North London outfit since his arrival in the summer, making a total of 11 appearances in all competitions.
However, when finalising terms for the 23-year-old, Spurs agreed to Real's request that a £41m buy-back clause must be included in his contract.
According to Bernabeu Digital, Los Blancos are already giving thought to activating that option during the summer transfer window.
While sales would need to be made to accommodate Reguilon's return, the La Liga champions require a long-term replacement for Marcelo.
Reguilon has previously suggested that he is open a second spell to the Bernabeu in the future.
