Questioning Ronaldo is an insult - Aduriz

The 34-year-old striker, who has been mooted as a possible pick for Vicente Del Bosque's Spain squad at Euro 2016, has defended the Real Madrid superstar from his critics

Athletic Bilbao striker Aritz Aduriz claims questions over Cristiano Ronaldo 's form in La Liga are "insulting" to the Real Madrid forward.

Ronaldo has scored 30 goals in 29 games in all competitions this season but doubts over his form have been raised in 2016, with the Portugal captain failing to find the net in four of his last six league matches.

The 31-year-old was disappointing in Madrid's 2-1 win over Granada on Sunday but Aduriz, who has scored 25 goals in all competitions this term, says neither Ronaldo nor Lionel Messi should questioned given their respective records.

"Can Cristiano be questioned? It seems like an insult to me. We can't question him for anything in the world," he said, as quoted by AS .
