Manchester City and Real Madrid are tracking Real Betis left-back Junior Firpo, according to the Mirror.

Blues boss Pep Guardiola has been monitoring 22-year-old Spainiard, who has been heavily linked with Real Madrid as a long-term replacement for Marcelo, who turns 31 this season.

Firpo, who was born in the Dominican Republic, has played for Spain at Under-21 level and is seen as a future Spain international.
