The midfielder says that his side was simply undone by the Reds on Tuesday night
Sergio Busquets says Tuesday was an absolute "failure" for Barcelona as the Spanish side collapsed once again in the Champions League, falling 4-0 to Liverpool on Tuesday.
Barcelona went into Tuesday's clash at Anfield nursing a 3-0 lead after Lionel Messi helped guide his side to a battering of Liverpool at the Camp Nou.
That lead unraveled rapidly, beginning with an early goal from Divock Origi, even if Barcelona still looked comfortable for a majority of the first half.
