The former Real Madrid left-back is in his second season with Spurs where the Los Merengues have a buy-back option.
However, Cataluyna Radio’s Carles Domenech is reporting Barca are keen to bring Reguilon back to Spain this summer.
Barca are in the market for a new left-back and see Reguilon as an attractive option.
He would arrive as competition for Jordi Alba.
