Cristiano Ronaldo's disappointing World Cup ended on a sour note as he was caught spitting towards a cameraman following Portugal's 1-0 loss to Spain in the second round.Portugal captain Ronaldo reacted angrily to the cameraman's attempts to follow him off the pitch in close proximity immediately after the final whistle, waving him away before spitting in his direction while looking down the barrel of the camera, an act that was broadcast around the world.While he was taking his frustration out on the man behind the lens, Ronaldo's spit appeared to the global audience to be directed towards them in an ugly act that could upset many of the fans of one of football's most marketable men.Ronaldo failed to fire in the tournament, scoring just once in Portugal's 7-0 thrashing of DPR Korea and otherwise lacking involvement as his side went scoreless in their other three matches.After the match, he told reporters to "talk to Carlos Queiroz" about Portugal's elimination from the World Cup. During the second half of the second round match, in which David Villa scored the only goal not long after the break, Ronaldo appeared frustrated as Queiroz issued a string of tactical instructions from the sideline that ultimately failed to bring Ronaldo, or Portugal, into the game.Credit: Soccernet.com
