Atletico Madrid advanced to the round of 16 after a tightly fought 3-1 win in Portugal, which sees Porto drop into the Europa League.
Luis Suarez’s night ended early after he was replaced by Matheus Cunha in the 13th-minute. It looked as if the tearful Uruguayan picked up a knock in the opening minutes.
Atletico Madrid had a great chance to take the lead in the 23rd minute. Antoine Greizmann had an empty net to aim at after a ball from Yannick Carrasco fizzed across the goal via a deflection off Thomas Lemar at the front post, but Griezmann could not quite connect as he arrived in behind.
Porto had a flurry of chances towards the end of the first period, but Jan Oblak kept the scores level as the team’s headed for the break after a string of important stops.
Atletico took the lead just before the hour mark through Griezmann. Lemar swung in a corner that met the head of Geoffrey Kondogbia, whose flick-on found Griezmann unmarked at the back post who was able to tap Atletico on the opener.
The game spiralled into chaos as a fight broke out after Carrasco was shown red for grappling his opponent by the neck and throwing him to the ground. Porto substitution Wendell was also sent off in the aftermath.
Angel Correa broke away from a struggling Porto defence and buried a second in the 90th minute to double Madrid’s lead. It was game over when Rodrigo de Paul fired in an effort from close range to make in 3-0 deep into added time.
Porto pulled a goal back in the final seconds through a Sergio Oliveira penalty, but it would only be a consolation.
