I really can't understand all the whining from the Liverpool fans about that game, besides a case of bad losing. Luisão should not by any means be sent off by that tackle to Torres. He tried to get to the ball, Torres protected the ball. Was it a bad tackle? Yes, but not like he went right to the leg. David Luiz could have been booked by constant fouling, but his first yellow card was just plain stupid. Yellow card because he kicked the ball? On the other hand, Torres should have been booked to for constant diving and whining (I love Torres but he is as much a great player as a big diver), Insua should have been out at the first penalty as he had already been booked and should got his second yellow card there, Cardozo got kicked in an obvious foul, which would be a penalty but the ref passed on that, and you can't really argue about the second penalty. He had no other purpose to have his hand there than to cut the passing angle. Reina had been wasting time since the first minute, even if in that particular time he hadn't been wasting that much (even through he took like ten more seconds to kick the damn ball after given the second order to do it). The only thing I agree with you was the Babel sent-off. Bit harsh there, but the rules are with the ref there who may have seen it as violent behavior.
About Benfica being one of the top 5 teams right now, it's a bit too much. Until December I would say so, but we are losing gas every week. See Cardozo. In another night he could have scored two/three more goals there with all the chances he had, and Liverpool would have suffered the same fate Everton did, but you see them tired. We also miss the energy Saviola had in the beginning of this season and Aimar isn't doing great too (hell most fans have been preferring Martins).
