Atletico have been touted as this season's dark horses, but they have suffered a worrying slump in form since finishing second to Liverpool in Group D.
The Primera Liga side have lost six of their last 10 matches in all competitions and coach Javier Aguirre was replaced by Abel Resino three weeks ago.
In contrast, Group G winners Porto have hit their stride and will arrive at the Vicente Calderon hoping to take a huge step towards surpassing two successive exits at the first knockout hurdle.
Jesualdo Ferreira's team finished above Arsenal in the group stages and gave an indication of their ability when recording a 2-0 home victory over a youthful Gunners side in December, which secured top spot.
Threat
Atletico's star man remains Argentine youngster Sergio Aguero and Resino will place his faith in the skilful playmaker as he attempts to down Porto.
Simao Sabrosa will also pose a threat in midfield, while former Manchester United striker Diego Forlan and ex-Liverpool forward Florent Sinama-Pongolle will be familiar faces to fans of the Premier League.
Luis Garcia, who has also spent time at Anfield during his career, continues his recovery from a hamstring injury, but Atletico should welcome back Ever Banega after the midfielder missed Saturday's 1-0 defeat at Sevilla with a knee complaint.
Luis Perea, victim of a fractured cheekbone against Sevilla, is suspended.
Porto are unbeaten in 12 games in their domestic league and the Portuguese champions travel to Madrid having won five of their last 10 away matches in the Champions League.
Ferreira, though, will be without midfielder Freddy Guarin (ankle) and defender Nelson Benitez (groin).
