Cristiano Ronaldo has not been affected by Juventus' recent struggles, insists Portugal head coach Fernando Santos.

The Bianconeri were eliminated from the Champions League in the last-16 stage by Porto a fortnight ago, going out on away goals after the tie finished 4-4 on aggregate after extra time at the Allianz Stadium.

Former Juve boss Fabio Capello singled out Ronaldo for criticism, while ex-president Giovanni Cobolli Gigli suggested the club should never have spent €100million to sign the forward in 2018.

Andrea Pirlo's side bounced back from that defeat with a 3-1 win over Cagliari in Serie A, but their hopes of securing a 10th consecutive Scudetto were left in tatters at the weekend following a shock 1-0 home loss to Benevento.
