Chelsea boss Thomas Tuchel admits they face an in-form Real Madrid this week.
The two teams meet in the first-leg of their Champions League semifinal.
Tuchel is under no illusions about the size of the task facing the Blues in Madrid.
"When you play against Real Madrid, it cannot be harder because they are the most experienced team in this competition," he said. "They're on a good run at the moment, 16 games unbeaten or something like that, so they will play these games with full confidence and full awareness.
"I hope we can play adventurous and aggressive football. We will fight them hard and then let's see who gets the win out of these two games. It's a big challenge but after we will be smarter and better because this will be a huge experience together.
"When you are a little boy, you dream about games against Real Madrid and now it's here so we are very happy to arrive in a situation on this level."
