Sergio Reguilón is reportedly considering leaving Tottenham Hotspur in the winter transfer window due to limited playtime under coach Ange Postecoglou. Real Sociedad, who are participating in European competitions, have shown interest in enhancing their defensive lineup and have reached out to Reguilón's representatives about the possibility of a return to Spain. The proposed arrangement might involve a loan with an option to purchase, providing Reguilón the opportunity to regain his form in a familiar setting.
