The Sun reports that Real Madrid could make a move for Zabaleta if they fail with a proposed bid for Chelsea’s Cesar Azpilicueta in the January transfer window.
Real Madrid have reportedly been impressed by Zabaleta’s consistent displays.
City are reportedly desperate to keep Zabaleta at the club, but the player himself could decide to push for a move.
Real Madrid have also been strongly linked with a move for City striker Sergio Aguero.
