Atletico Madrid won a bad-tempered game in Porto on Tuesday to qualify for the last 16 of the Champions League as Liverpool and Ajax both completed the group stage with 100 percent records. Diego Simeone's Atletico, who lost to Real Madrid in the 2014 and 2016 finals, needed to beat Porto in Portugal to advance to the knockout phase and they duly triumphed 3-1 in a game which featured three red cards. Antoine Griezmann put the Spanish champions ahead in the 56th minute at the Estadio do Dragao but they then had Yannick Carrasco sent off for wrestling Otavio to the ground.
