the ref was olegário benquerença
anyway, things always get even and simão could have also been sent off after tackling n'doye from behind and, consequently, be out of the derby against Sporting. I keep saying that Benfica, and teams in general, lose more points due to their own tactical/technical mistakes than from referees'.
What I really think it's urgent to fix is the way every guy talks about referees during the week without any punishment. In the latest weeks, José Couceiro, Pinto da Costa, Dias da Cunha, José Veiga (just to mention three or four) have always been pressing referees, mainly the ones involved in Benfica matches, and there is not anyone who punishes them. This way, they indirectly have influence in the referees' jobs and Portuguese football credibility in general.
