Real Madrid have Ferland Mendy and Marcelo, two players Zinedine Zidane trusts, making Reguilon available.
19-year-old Miguel Gutierrez will also be promoted to the first team soon after extending his contract in March.
With that in mind, Madrid are open to selling Reguilon, but would ask for a 25% sell-on clause and first refusal.
Another idea is for Madrid to sell him, but with a fixed option to buy him back, like when Alvaro Morata moved to Juventus.
Juve & Sevilla also want Reguilon
Kia Joorabchian, Reguilon’s new agent, has been inundated with offers for the Madrid homegrown star.
Juventus are also keen on Reguilon, while Sevilla want him back on another loan deal.
Man United are willing to pay €30m plus bonuses, a proposal currently being studied at Real Madrid headquarters.
The English team want to strengthen a position where they only have Luke Shaw and the inexperienced Brandon Williams.
