AC Milan frustrated Barcelona in its attempt to grab a valuable away goal in the Champions League on Wednesday night, holding the defending champions to a 0-0 draw while Bayern Munich won 2-0 at Marseille to stay on course for the semifinals.
Barcelona had 62 percent of possession but failed to score in a Champions League match for the first time in 2½ years. When Barcelona did create chances at San Siro, it was thwarted by Milan's experienced defense, goalkeeper Christian Abbiati and some lenient refereeing from Jonas Eriksson.
The closest Lionel Messi came to scoring was when he had a first-half goal ruled out for a clear offside.
Mario Gomez and Arjen Robben scored in the first leg of Bayern's quarterfinal in France.
