A second-half header from Yossi Benayoun was enough to stun the Santiago Bernabeu crowd on Wednesday and give Rafael Benitez's men a crucial away goal edge.
"Now we have a goal disadvantage. There's still a second leg to play but I think it'll be difficult to win the Champions League or any other tournament this season," Ramos was quoted as saying by Marca.
Harsh Result
Despite admitting that Real have slim chances of turning around the tie at Liverpool, Ramos said that the 1-0 defeat was a harsh result for his team.
"It was a very tight game, and Liverpool just waited for their opportunity to score and in the end, they took advantage from a set-piece and got their goal.
"However, I believe this game should have clearly ended 0-0," added the former Tottenham coach.
Failed Attempts
Ramos added that he did his best to boost his team's performance in the second half, but Liverpool didn’t leave Los Merengues any chance to play their attacking game.
"We knew it was going to be a very tactical game. They defended very well and closed off all our attacking routes, especially in the centre of the field.
"This is why I brought in Guti at half-time, to give us more depth. But they had two lines of defence and they just wouldn’t let us manoeuvre to find space."
