Atletico Madrid v Bayern Munich: Thomas Muller has prepared for Atletico's 'antics'
Thomas Muller says Bayern Munich will have to cope with Atletico Madrid's 'antics' during tonight's Champions League semi-final first leg.
In the previous two seasons, the German side have been knocked out of Europe's premier competition by Spanish teams at the last-four stage and high-flying Atletico are expected to offer a stern test at the Vicente Calderon.
Diego Simeone's side have become renowned for their physical approach, and Muller says Bayern must not be intimidated.
"We have our eyes wide open," said Germany forward Muller. "There will be antics and many one-on-ones in the grey area. We'll have to adjust to it."
Bayern boss Pep Guardiola added: "They have a big heart and a very good mentality. This is a top, top team. They are very, very dangerous.
"I know exactly how special Atletico's team is and how much determination they play with."
Robert Lewandowski, meanwhile, has said he might play in England or Spain one day but he is happy at Bayern for now.
Lewandowski, 27, is having another standout season in Germany, having scored 27 league goals and eight in the Champions League so far.
"Maybe I'll play in England or Spain one day but, if I committed to pursuing my career in Munich, it's because I considered it the ideal club at which to move up a level and to win trophies," Lewandowski said.
"The fact that every season they reach at least the semi-finals of the Champions League impressed me.
"I don't know what my future will look like but at the moment I'm very happy at Bayern."
