Liverpool fans made their feelings known to club co-owner Tom Hicks after their victory over Bolton Wanderers.
The Sunday Mirror says an angry mob of more than 200 gathered outside the main entrance for 90 minutes after the game chanting "Yank The Liars Out" after Hicks watched the win.
Hicks was effectively trapped inside the stadium after club officials advised him to stay put rather than risk a explosive confrontation.
An insider said: "He has been told to stay in the directors' lounge for his own good. The protesters have all the exits covered."
