Real Madrid goalkeeper Iker Casillas warned there could have been "serious" consequences for Atletico Madrid after Cristiano Ronaldo was hit on the head by a lighter thrown from the stands in Tuesday's Copa del Rey clash.
Two early penalties from Portugal forward Ronaldo earned Carlo Ancelotti's side a 2-0 win at the Vicente Calderon, securing a 5-0 aggregate triumph in the two-legged semi-final.
Ronaldo's reward was to be struck by a lighter as he walked off at half-time alongside Sergio Ramos, and, although he was not seriously injured, Casillas felt it could have turned out a lot worse.
"There is always someone that tries to smear the image of a club like Atletico Madrid and it doesn't reflect how the majority of their fans are," he said on www.realmadrid.com.
"I think the consequences could be serious, because it could have hurt a player."
Ronaldo played for the remainder of the match and left at full-time as a winner, and with the praise of coach Ancelotti soon ringing in his ears.
"Cristiano is doing well. He scored two goals and played a key role at the start of the match. The three forwards did well at the start and were very dangerous."
