Barcelona:Chelsea held Barcelona to a 0-0 draw on Tuesday in the first leg of the Champions League semi-finals.
Both goalkeepers made important saves to preserve the draw at the Camp Nou, with Victor Valdes making a reaction save on a shot from Didier Drogba following a Barcelona defensive lapse in the 39th minute.
Chelsea goalkeeper Petr Cech dove to keep Samuel Eto'o's shot out in the 70th after the Barcelona striker had shook off Alex to get a clear chance from close-range.
The English club is the first to hold Barcelona scoreless since the Spanish league leaders lost to Numancia 1-0 on the opening day of the season.
The return leg will be played at Stamford Bridge on May 6.
