Neymar is coming to the end of an injury-hit second season at Paris Saint-Germain and the opening of the transfer window could bring fresh speculation about his long-term plans.
Madrid have been credited with an interest in the Selecao star since his departure from Barcelona in 2017 and are expected to adopt an aggressive recruitment approach under Zinedine Zidane in response to an underwhelming campaign.
Ronaldo played alongside Zidane for Los Blancos and believes his old team-mate has little chance of prising attacker Neymar away from PSG.
