Defender Filipe Luis maintains Atletico Madrid are still alive in their Champions League quarter-final against Barcelona.
Fernando Torres put Atleti ahead on 24 minutes but was then shown a red card after collecting a needless second caution. A second-half brace from Luis Suarez then gave Barca a 2-1 first-leg win.
But the home side, who had seen their long unbeaten record ended following a late defeat at home by 10-man Real Madrid in El Clasico on Saturday, were not able to capitalise further.
And Luis believes that leaves the tie very much in the balance ahead of the second leg at Vicente Calderon on April 13.
Luis said: "We had our chances, but we always knew it was going to be really difficult, but we think we are still alive.
"They won, they have the result on their side, they had a lot of chances and fortunately for us they only scored two goals, so it could have been worse.
"We are still alive, we have to win now. It is possible but it will be really difficult."
Luis was unhappy with the decision of German referee Felix Brych to dismiss Torres.
"It was a totally unfair red card, his second foul and his second yellow. We knew that was going to happen, it being Barcelona in the Champions League. We have to play against everybody and everything," he added.
"The manager said we needed an epic game to win. Now it will be difficult but we are still alive."
Barca boss Luis Enrique hailed the efforts of his men.
"We must appreciate how difficult (it is to) play against Atletico. With this attitude and these players we will go to the end of the world," he said afterwards.
Atletico Madrid manager Diego Simeone believes the visitors remain very much in the tie.
"Beyond the inequality there was in the match, we leave with a situation that allows us to have hope," he said.
"I am very happy with my team. Once again, we started winning, we were doing very well."
Bayern Munich will take a slender 1-0 lead to Portugal after an organised defensive display from Benfica at the Allianz Arena in the first leg of their quarter-final.
Arturo Vidal's second-minute goal was all that separated the two teams.
