Gareth Bale is looking forward to the first leg of their quarter-final Champions League tie against Bayern Munich on Wednesday.
The former Tottenham attacker is convinced the match between Los Blancos and the Bavarians at the Allianz Arena will be a difficult game and an away goal will be key for Zinedine Zidane's side.
"It’ll obviously be a huge game as they are such a dangerous and well-established team," Bale told Goal.
"With the first leg being in Munich we really need to try score an away goal and defend well, so that we can make the most of the second leg being at the Bernabeu."

Speaking of his former boss Carlo Ancelotti, the Wales international said: "If you look at the past three Bayern managers, each of them has introduced something a bit different without their approach affecting the success of the team.
"Ancelotti has probably made them a bit harder to beat but they are still deadly going forward.
"He’s a great manager so you expect him to make an impact and be successful wherever he goes."
