Cristiano Ronaldo has pinpointed Bayern Munich's frontline as their most potent weapon ahead of Real Madrid's Champions League semi-final second leg at the Bernabeu.
Real trail Bayern 2-1 after Mario Gomez struck a late winner at the Allianz Arena - the venue of May's final - and the pair lock horns once again on Wednesday.
Jose Mourinho's side will head into the game buoyed by Saturday's triumph over Barcelona in El Clasico, but Ronaldo is wary of Bayern, in particular their attacking prowess.
Asked which Bayern player worries him most, Ronaldo told Bwin: "The players who play up front concern us most. Gomez is one of the leading goalscorers in the Champions League, and (Franck) Ribery and (Arjen) Robben are also very dangerous.
"They are very good up front, and at the back as well, but we have to be focused on the four in attack because it is one of them who will make the difference."
Nevertheless, the Portugal international is confident it will be his side progressing through to next month's final in Munich as Madrid seek a record 10th European Cup crown.
"We are well. I'm sure that at home we are going to win because we are playing in our stadium, in front of our own fans and we have everything we need to be able to win," he added.
"It's going to be a very difficult game, but I'm hopeful of a Madrid win. They played at home and won, but we got a goal there, which is also important.
"We know that Bayern, after the first leg, are to going to play on the counter-attack, but we also believe that they are going to have a lot of respect for us because we are playing at home.
"I hope we reach the final because it is very important to us players, to Real Madrid and to our fans throughout the world."
