Two penalties by Brazilian midfielder Siqueira allowed Granada to come back and draw 2-2 away at Getafe in the Spanish league on Monday.
Getafe was the sharper side at the start and Juan Rodriguez scored by heading in a free kick taken by Adrian Colunga in the 19th minute.
Granada was then awarded a penalty in the 28th after Argentine midfielder David Abraham handled the ball in the six-yard box and Siqueira converted the spot kick.
Francisco Alcacer restored Getafe's lead in the 42nd by lobbing over Granada goalkeeper Roberto Fernandez after controlling Colunga's overhead back-pass.
But Getafe left back Rafael Lopez deflected the ball from a corner with his hands in injury time and Siqueira stepped up again to convert the penalty.
