Real Madrid star Cristiano Ronaldo has lit the blue touch paper ahead of Portugal's Euro2012 semifinal clash with Spain. Ronaldo, according to El Mundo Deportivo, has taken a swipe at Spain's Barcelona players and their Catalan roots leading up to the big game.

"I, at least, I am Portuguese, not like some internationals of Spain who are not Spanish," Ronaldo is quoted as taunting Spain's players.
