Lol, that Atalanta call is really hilarious. Yes, Marchionni was offside, but he was offside some 40 metres from the goal, next to the line. He needed to make a cross 25 metres from the goal, it took two Atalanata players to miss the ball (and no good defender would have missed to clear that weak cross), so Del Piero could get the ball and score.
The chances Juve to score from that action were what? 1/20? 1/50?
It must be tough for other teams not to have many excuses about Juve's wins anymore.
But Baptista said it with a reason. He was probably told to say that. It's very important match for Roma and they need a referee who will be afraid that he'll be accused of helping Juve if he gives calls in our favor.
Actually, looking at Roma's available players, Roma will need all the ref help in the world to win the match.
