Ander Iturraspe says Real Madrid's Cristiano Ronaldo is "from another planet" after he scored his third hat-trick in four games in the 5-0 demolition of Athletic Bilbao.
His tally for the season now stands at 13 goals from just six matches to put him out in front as the standout candidate to win a third Ballon d'Or.
Bilbao midfielder Iturraspe had the misfortune of watching Ronaldo at close quarters during the encounter however, was generous in his praise of the Portugal star.
"Cristiano Ronaldo is a player on another level, on another planet," he exclusively told Goal.
It was a fary cry from the last meeting between both clubs, when Ronaldo was sent off after becoming embroiled in a confrontation with Iturraspe in the 1-1 draw at San Mames last term.
He added: "With Cristiano Ronaldo things were completely normal, despite what happened last season. I met him at all the set pieces and there was plenty of respect. There were no problems."
Bilbao have struggled in La Liga so far this term after finishing fourth in the division in 2013-14, and Iturraspe admitted they have felt the summer loss of Ander Herrera to Manchester United.
"He spent three years with us and was a key player for the Athletic. He is a great friend. However, he is not with us now and there are other great players we've to rely on."
