Bayern Munich sent out an emphatic and ominous message to their Champions League rivals, with an absolute demolition of fellow European heavyweights Barcelona in a gloriously chaotic and utterly one-sided quarter-final tie in Lisbon.
The high-pressing, energetic and ruthless German champions scored four times in the first half, added another quartet in the second, and could easily have netted more against a shell-shocked and shambolic Barcelona side whose defensive errors were too numerous to recount and now have a new and embarrassing record defeat in European competition to their name.
