"If I've a certain attitude it's simply because I have always had it and will continue to do that. I play for the team and not to show off," the Portuguese prodigy told Skysports.com.

Pizarro was booked for a challenge against Ronaldo who was showing some of his amazing footwork just before the break.

"On the field I respect my adversary. If someone thinks my moves are mockery then they are wrong."

Ronaldo has been in a sensational form this season scoring 36 goals until now.
