Ronaldo wary of Bayern attack

Cristiano Ronaldo admits he is wary of Bayern Munich's attacking threat ahead of Wednesday's Champions League semi-final second leg.

The La Liga giants will need to overturn a 2-1 first-leg deficit if they are to proceed to the final and keeping a clean sheet at the Bernabeu will be vital to their cause. But Ronaldo does not feel that will be easy given the attacking talent on show in the Bavarian ranks. "The players that play up front concern us most," he said. "Gomez is one of the leading goalscorers in the Champions League, and Ribery and Robben are also very dangerous." The Portugal international feels Bayern are a strong all-round team but insist it is the front players who concern him the most. "They are very good upfront, 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," he added.
