On another intriguing night of Europa League action Everton's 100 percent record comes to an end in emphatic fashion and Villarreal's slump continues thanks to a last minute Lazio winner.
The pick of the early kick-offs saw David Moyes' Everton side travel to Lisbon to take on Benfica, the first of three away trips in just six days.
Having won their opening two games in Group I, the Toffees were full of confidence going into the match, but Benfica's South American superstars ripped them apart and administered a 5-0 hammering at the Estadio da Luz.
Braces from Paraguayan Oscar Cardozo and Argentinian Javier Saviola along with a trademark header from Brazilian Luisao and a man of the match performance from Liverpool target Angel Di Maria destroyed a makeshift Everton side and sent As Águias to the top of the group.
Elsewhere in Group I, BATE Borisov earned their first points of the campaign after a 2-1 win over AEK Athens in Minsk.
Serie A giants Lazio had substitute Tommaso Rocchi to thank for an injury time winner against Villarreal at the Stadio Olimpico.
The 2-1 defeat means the Yellow Submarine are still awaiting their second win of the season having made a disastrous start to the campaign, a win over Levski Sofia their only victory in any competition so far.
The pressure is mounting on boss Ernesto Valverde, who has made a terrible start after succeeding Real Madrid boss Manuel Pellegrini at El Madrigal.
