Oldref...I agree that one blown call is a bit harsh of a standard, but here we have MULTIPLE blown calls...all within a ten minute span, that lead to a game changing decision. Not only does Carballo make mistakes in assessing whether a foul occurred (bad angle?/ bad distance?) but he also makes tragic mistakes in an area where he has great discretion...namely the giving of cards. And when he DOES give a card (the 2nd yellow), he gives the wrong color b/c apparently didn't possess enough awareness to know it should have been a straight red, had a foul actually occurred. These types of mistakes do NOT inspire confidence in his overall ability. Contrast that with Webb's blown pk call in the very next match. Nobody said a PEEP. Why? Because Webb, looked at it, analyzed it, and waved play on. He was in total apparent control. Carballo, on the other hand, looked like a lost puppy. Its no coincidence that Holevas got another yellow a few minutes later and the Greek players were all over Carballo about a caution in a non critical time in the match and in a non critical spot on the field to one of their fringe players ........ that was 100% correct . At this point, NOBODY was buying anything of what Carballo was selling. That's a very dangerous spot to be in as a ref. I also didn't like the manner in which he banged Holevas with a card. After you've given two incredibly soft yellows to teh same player AND dismissed a pk claim, the last thing in the world you want to do is so forcefully and emphatically show a card to a player who hasn't been a problem all game long...for a frickin tactical foul.
