The ex-Spain international right-back believes the Real Madrid ace's contribution is undervalued, insisting the Portuguese forward's hard work often goes unrecognised
The Portugal star recently became Madrid's all-time top goalscorer in La Liga and extended his Champions League goal record to 80 after yet another hat-trick, this time against Ukrainian side Shakhtar Donetsk in a 4-0 win.
However, despite accomplishing this astonishing feat, Salgado believes not everybody realises how much work Ronaldo puts in to achieve his success.
"How he works is spectacular and what he’s doing is impressive, equalling Messi's records and winning Ballons d'Or when it's so difficult, because you have a player like Lionel Messi," Salgado told AS .
"I don’t think people realise the value of Cristiano and the effort he puts into winning what he wins."
Salgado made more than 250 appearances at right-back for Madrid during his career, a position now held by Dani Carvajal, and the retired defender is full of praise for the 23-year-old.
"For me, Dani Carvajal is a special full-back and is amazing in defence and attack and has the perfect balance," he added.
"He's a player who has learned to defend over the past two years at Real Madrid. He has quality, gets down the other end, can put in a good cross and is currently first choice for both real Madrid and Spain."
