Arjen Robben believes Bayern Munich will have to play "the perfect game" to overcome Real Madrid in their Champions League semi-final at the Allianz Arena on Tuesday night.
Bayern are fully focused on winning a fifth European crown on home soil after losing to Bundesliga-leaders Borussia Dortmund last week and effectively writing off the German title to rest key players in the 0-0 draw with Mainz at the weekend.
Robben says Bayern are now ready to take on one of Europe's best teams and told Marca: "We will give everything. You will see a great Bayern, I'm sure. We have no doubt that to eliminate Madrid, we will have to be at 120%, at our maximum, and play the perfect game."
The Dutchman played under Real Madrid coach Jose Mourinho during his time at Chelsea and despite all the stars Los Blancos can put on the pitch, Robben believes it is the man in the dugout that gives the Spanish side their swagger.
"They have incredible quality in attack," Robben said. "There are no secrets about Madrid. But the most important things is that they have the best coach, who always knows how to play these games."
Robben not only has an insight into Mourinho's approach, but also knows Real well, having played for the club for two seasons until 2009. However, the Netherlands international insists he is not thinking about his past, only the job in hand.
"I had some very good years at Madrid. It's a great club, and it's obviously special to face my old team-mates, but I have been at Bayern for a while now and I am happy here," he said. "I am thinking above all about getting to the final, whoever the opponents are."
Meanwhile, Bayern's influential midfielder Bastian Schweinsteiger, who is still easing himself back to full fitness after an ankle injury, believes his team's only hope is to go on the attack.
"It's all or nothing. We have to go to the limits and beyond but we can do it with our fans behind us," Schweinsteiger said. "It won't be easy and it comes down to mental strength. I hope we can show the mentality which marks Bayern out."
