Sergio Ramos: Real Madrid's win over PSG 'not at all comfortable'

Real Madrid captain Sergio Ramos said the team would have to "reflect on the mistakes we have made" after Tuesday's fortunate 1-0 Champions League win over Paris Saint-Germain at the Estadio Santiago Bernabeu.

Madrid were outplayed during the first half but still went to the break 1-0 ahead thanks to a surprise goal from reserve defender Nacho Fernandez and a string of misses from PSG frontman Edinson Cavani.

Rafa Benitez's side were better after the break, and came close to a second through midfielders Isco and Toni Kroos, but former Madrid winger Angel Di Maria was inches away from equalising when he struck a late free kick off the crossbar.

Madrid have now qualified for the Champions League knockout stage with two games still to play, are joint-top of the La Liga table, and remain unbeaten in all competitions during 2015-16.

However, Blancos centre-back Ramos told Spanish TV channel Antenna 3 that his team -- who drew 0-0 in Paris last month -- needed to think about the mistakes they had made in the game.

"It was not at all comfortable, and it is true that there were some good things," Ramos said. "We have a lot to reflect on.

"We played a better game there [in Paris] -- you play better and you take just one point -- and here you play worse and you take all three. Football has this, and you would always take a win. We must be happy to be practically qualified and must reflect on the mistakes we have made."

Madrid also saw in-form left-back Marcelo pick up a hamstring injury midway through the first half.

Ramos said he hoped the latest injury for Madrid, who have seen 12 different players miss games over the last month, would not prove too serious.

"That is the worst news -- [Marcelo] was in his best form," he said. "We hope it is nothing, and that he is OK to play for Brazil and for the Clasico [against Barcelona on Nov. 21]. Hopefully we can empty the treatment room. We are not stopping."
