Liverpool ended their worst sequence of results since 1987 and eased the pressure on manager Rafael Benitez in the most satisfying manner possible as Manchester United were deservedly beaten at Anfield.
Fernando Torres demonstrated his world class with a 65th-minute opener, comfortably shrugging off the attentions of Rio Ferdinand before powering an unstoppable finish high past United keeper Edwin van der Sar at The Kop end.
And after United's Nemanja Vidic was sent off for the third successive time against Liverpool and Javier Mascherano also saw red in a thunderous finale, substitute David Ngog raced on to Lucas's pass to wrap up a fully-merited victory.
Anfield was awash with ecstasy as goalkeeper Pepe Reina rushed the length of the field to join the celebrations with Ngog - a sign of what was riding on this result for Liverpool and manager Benitez.
Reds boss Benitez entered this crucial game with spirits lifted after managing director Christian Purslow added his weight to co-owner George Gillett's message that his future is not under threat.
But it was the commitment and energy shown by Liverpool in the face of four successive defeats that was always going to be the most realistic measure of the current circumstances surrounding Benitez.
And Liverpool delivered in emphatic fashion, backed by fervent Anfield supporters who recognised Benitez had reached a pivotal point in his five-year reign.
Liverpool held sway for most of a match that only occasionally touched the heights, but the workload of the respective keepers confirmed this was a victory well-earned by Benitez's side - and which now leaves them only four points behind the Premier League champions. (BBC Sport)
