The Portuguese forward's club colleague, Gareth Bale, has also faced questioning regarding his contribution since returning from injury
Cristiano Ronaldo has lost his “absolute hunger” for goals, according to former Real Madrid boss Bernd Schuster.
The Portugal international has been a prolific marksman for over a decade now, with his first return of 20-plus achieved while with Manchester United in 2006-07.
A record-breaking transfer to Spain in 2009 helped to take his game to another level, with a remarkable 390 efforts plundered in just 384 appearances for Madrid.
His strike rate has, however, slowed this season and he has just one goal in his last five appearances at club level, with Schuster suggesting that his once all-encompassing desire to be the best is fading.
