That's according to Okdiario's chief pundit Eduardo Inda, speaking on El Chiringuito.
Reguilon left Real Madrid for Spurs three weeks ago.
And Inda says: "Reguilón shares a representative with (Philippe) Coutinho, and when he was negotiating the return of the Brazilian, he found out they were in Barcelona looking for cover for Jordi Alba and they asked him about Reguilón.
"He proposed it and Reguilon answered: 'How am I going to go to Barça if I'm more of a Madridista than Santiago Bernabéu?'."
Reguilon and Coutinho's agent is Kia Joorabchian.
