The Portuguese ace wasn't able to score from the spot once again during his National Team's warmup match against Bulgaria.

Cristiano Ronaldo's problems from the spot continued today, as the Portuguese superstar missed yet another penalty kick during the friendly between A Selecçao das Quinas and Bulgaria.

Ronaldo's penalty was saved by Vlado Stoyanov, which helped Bulgaria prevail against the Portuguese team, one of the teams that's expected to be among the top performers of the Euro 2016 tournament.

Marcelinho gave Bulgaria the lead after 19 minutes, taking advantage from some sloppy defensive skills shown by Pepe. As CR7 failed to equalize during the first half, the chance to transform the penalty came after the 67th minute, but his miss ended up costing Portugal the game.
