Liverpool cruised into the fourth round of the Carling Cup at the expense of Millwall in a match overshadowed by violence in the stands.
Salif Diao and Milan Baros were the scorers for Liverpool - who for long periods reduced Millwall to speculative punts upfield in lieu of attacking moves.
The match was marred by ugly brawls in the stands late in the game, when fans in the visitors' section began ripping out seats and attempted a pitch invasion - but police soon quelled the trouble.
Diao scored his first goal in almost two years in the 18th minute with a well-taken outside-foot shot which rattled in off the post from 15 yards out.
And substitute Baros added two more for Liverpool, the first on 70 minutes with the easiest of goals after Graham Stack was caught way off his line, before rounding off the win with an injury-time effort.
Five minutes before kick-off Millwall paid tribute to radio DJ and lifelong Liverpool fan John Peel, who died on Tuesday aged 65, by playing his favourite song, The Undertones' Teenage Kicks.
Liverpool, League Cup winners in 2003, served notice of how trivially they regard this year's competition - and opposition - by making no less than ten changes to the side that beat Charlton 2-0 at the weekend.
Djimi Traore was the only survivor from the Reds' previous match, while Zak Whitbread, a 20-year-old from Texas, got his first taste of senior action, partnering Stephane Henchoz in the centre of defence.
Midfielder Darren Potter was up against English opposition for the first time in his career - his only previous first-team experience coming against Graz AK in August.
Millwall, players and fans alike, were definitely up for the cup. The Den was at full capacity for the first time since their ill-fated play-off semi-final against Birmingham three seasons ago, and the team was at full strength.
Player-manager Dennis Wise watched the match from the stands, while Josh Simpson and the cup-tied Barry Hayles were the only others to be dropped from Millwall's 2-2 draw with Cardiff four days ago.
Neil Harris, playing wide on the left for the Lions, could have had a hat-trick if his luck and first touch had been better.
Harris provided the first opening of the game when he broke through only to take one touch too many and roll the ball into the hands of Dudek.
But he went close to an equaliser in the 23rd minute when he was freed by Jody Morris' quickly-taken free-kick, but his close-range shot was again kept out.
And on 34 minutes he should have done better when he headed over the bar while unmarked just five yards out.
Midway through the first half Adrian Serioux - on his first start since recovering from a shoulder injury - threw a monster ball into the box, which was headed agonisingly wide of the post by Darren Ward.
