Barcelona players were verbally assaulted by angry supporters, as they returned to their hotel in Lisbon following their 8-2 whitewash against Bayern Munich.
The LaLiga giants suffered their heaviest ever Champions League defeat, as Bayern Munich ran riot to book their place in the semi-final.
Fans gathered outside the hotel to vent, with AS reporting some of them screamed "scoundrels", as the players disembarked from the team bus.
The likes of Luis Suarez, Nelson Semedo, Antoine Griezmann and Ivan Rakitic were subjected to boos, while Lionel Messi appeared to hold his hands up in apology.
Barca are now expected to take decisive action in the coming days, including sacking manager Quique Setien.
It is also believed that Sporting Director, Eric Ebidal, will join Setien in going through the exit doors.
