LONDON - Liverpool lost to a third-tier club for the first time in 20 years as they were dumped out of the FA Cup 3-2 by Oldham Athletic.

Leeds stunned Spurs and Brentford held Chelsea in a remarkable day.

Matt Smith's double helped earn League One Oldham a shock victory over seven-times winners Liverpool in a classic FA Cup encounter.

Leeds sent Tottenham crashing out of the competition with a 2-1 victory at Elland Road.

A late goal from Fernando Torres spared Chelsea considerable embarrassment as they were forced to twice come from a goal down to draw 2-2 away at League One Brentford in their fourth round encounter.

Cup holders Chelsea were poor for large swathes of the first meeting of these London sides since 1950, and went behind twice following mistakes from Ross Turnbull as Marcello Trotta thumped home a fine volley after the ball was parried into his path and Harry Forrester converted from the penalty spot following a foul from the Chelsea keeper.

With the hated interim manager Rafa Benitez contemplating the most humiliating result of his brief reign in charge, Oscar first rescued Chelsea with a gorgeous individual effort after 55 minutes, before Torres struck a second equaliser with seven minutes remaining to enjoy a redemptive moment, both for himself and his team.

But the story of the afternoon was a brilliant performance from Brentford, who will now reap the financial rewards of a replay at Stamford Bridge, even if they were unable to topple the cup holders for another cup shock.

Millwall, MK Dons and, most famously, non-league Luton Town had all disposed of Premier League opposition in a fine weekend for the south east's lower league contingent, but seeking to avoid similar humiliation Chelsea were reinforced by the return of captain John Terry, making his first start since suffering a knee injury in November.
