Holders Real have the advantage after their smash-and-grab 2-1 win in Munich a week ago, but were exposed defensively throughout the first leg.

"It's going to be a very difficult match," Ronaldo, scorer of 104 goals in 177 appearances for Real between 2002-2007, told Spanish radio broadcast El Larguero.

"Bayern are a big team, the tie is not over yet. They have players in every position that can hurt Real."

With Bayern needing to win by at least two clear goals to reach the final, the three-time Ballon d'Or winner also revealed his nerves can only handle watching the game from the comfort of his own home.

"I certainly won't be going to the Bernabeu," the 41-year-old admitted. "I'll watch it at home. That way I can control myself better."
