​Bayern Munich star Thomas Muller has urged the referee for ​his side's game against Real Madrid, Cuneyt Cakir, not to be influenced by the loud and noisy atmosphere in the Santiago Bernabeu.

The two sides take each other on in the second leg of the Champions League semifinal, with Real Madrid currently leading 2-1 on aggregate. The duo met in the quarterfinals last season and the tie was ​marred with some poor officiating in Madrid which saw Cristiano Ronaldo score from an offside position.

Muller, Bayern's stand-in skipper, was speaking in his pre-match press conference and the Germany star claimed that the officials must not let the atmosphere influence their decisions while also adding that he and his teammates must make the most of the chances they get, something they failed to do in the first leg.

As reported by ​Marca, Muller said, "Everyone knows what happened here last year, with two offside Madrid goals. And the Juventus penalty... the atmosphere should not affect the officials. We will concentrate on the game because we are already under too much pressure."

"We analysed the first leg to know how to face the return. We have to take advantage of our chances, be hungry to score goals and to hurt Madrid."

Muller was also asked about his attack partner Robert Lewandowski, a long-term target for Real Madrid. The 28-year-old backed his teammate to perform in the Bernabeu, claiming that his qualities cannot be questioned.

He added, "If we don't win and we don't score, we're not going to look for a scapegoat. Lewa's qualities are indisputable."

With ​Real Madrid winning 2-1 at the Allianz Arena, Muller and co. will have to score at least twice tonight to stand a chance of progressing to the final for the first time since they won the Champions League in 2013.
