Sergio Ramos has admitted Real Madrid did not play well in the 1-0 win over Paris Saint-Germain which secured their place in the Champions League knockout phase.
Rafael Benitez's team were outplayed for much of the match by PSG, who peppered the hosts' goal either side of Nacho's winning strike 35 minutes into the first half.
And Ramos conceded that while Madrid could be pleased with the result, their performance left a lot to be desired.
"We have achieved three points against a very important rival," the centre-back told reporters. "[But] we did not play well today.
"It was an uncomfortable game. We have a lot to reflect on."
Ramos also lamented the injury suffered by fellow defender Marcelo, who limped off injured in the first half to be replaced by Nacho minutes before the substitute opened the scoring.
"Marcelo's injury is a shame because he was in a good run of form," the Spaniard added. "Hopefully he can play against Sevilla."
