Inter club president Massimo Moratti stirred up a new controversy when he claimed that the referee was intentional to favor Juventus during the Serie A leaders\' 3-1 loss to Inter on Saturday. Arturo Vidal scored the first goal with only 19 seconds into play, but it was shown by the TV replay to be offside. Stephan Lichsteiner did not get punished for his vicious tackle. \"Continual mistakes from referees can happen, but we have to be very careful, because they cannot afford to make errors like that,\" said Moratti. \"The mistake on the offside goal was serious, but the second was intentional. All they had to do was pay attention to the tackle and it would\' ve been a red card.\" \"I don\' t make a personal matter out of it with the referee. Above all, it was the second mistake that was unjustifiable,\" he said.
