The Spain international has warned that a difficult task awaits Los Blancos in the return game against the Bavarians, and was quite disappointed with Tuesday's loss
Los Blancos were beaten 2-1 in the first leg of their semi-final tie at the Allianz Arena on Tuesday, and the defender feels that one goal in next week's return will probably not be enough to progress.
"We'll have to try to win the tie from the start. One goal may not be enough. We'll have to go all out for a win," Ramos was quoted as saying on the club's official website.
"Everyone at the Bernabeu must roar in support of the team and make our opponent feel what it's like to play at the stadium.
"It was a shame to lose. We would have liked to leave with a draw, but these things happen in football. We faced a dangerous opponent that has great individual skill."
The defender then looked ahead to the upcoming league clash against arch-rivals Barcelona, and insisted that Madrid want victory at the weekend.
"This is football: the Champions League and La Liga can be at stake for a team in no time. We want to win at Camp Nou."
Saturday's encounter between Barcelona and Real Madrid kicks off at 20.00CET.
