Real Madrid face competition for the signing of Real Betis defender Junior Firpo.
Real see Firpo as a long-term successor for veteran wing-back Marcelo and are willing to pay his €50m buyout clause.
However, El Confidencial says Manchester City are also keen, where manager Pep Guardiola is a fan.
And concerning for Real Madrid is City's advantage as Firpo's agent is Pere Guardiola, the manager's brother.
The situation could lead to Real president Florentino Perez moving immediately to meet Firpo's clause and close a deal before City have time to act.
