Champions League favorites Barcelona produced another devastating display to outclass Bayern Munich 4-0 at the Nou Camp and virtually guarantee a place in the semifinals of the competition. In the last round, the Catalan giants scored four first-half goals on their way to crushing French champions Lyon, and they repeated the trick on Wednesday as Lionel Messi (2), Thierry Henry and Samuel Eto’o again proved they are the most deadly strike-force in world football. German champions Bayern were thrashed 5-1 by Wolfsburg in the Bundesliga on Saturday and they looked to be heading for another mauling as early as the fifth minute when Henry rounded goalkeeper Hans-Jorg Butt — but his weak shot was cleared off the line.
