LONDON — Third-tier Oldham Athletic stunned seven-time FA Cup winner Liverpool with a shock 3-2 fourth-round win Sunday and Leeds United caused another big upset by knocking out Tottenham Hotspur 2-1 at Elland Road. Holder Chelsea was also heading for a surprise defeat at third-tier Brentford until Fernando Torres hit a late equalizer to salvage a 2-2 draw. Defeat for Liverpool and Spurs took the number of Premier League casualties losing to lower division opponents in the last 32 to five following defeats for Norwich City, Queens Park Rangers and Aston Villa. Oldham, languishing in 19th place in League One, was irresistible in front of its own fans at Boundary Park, going ahead with a Matt Smith header in the second minute. Luis Suarez leveled but Smith's second and a third goal from Reece Wabara made it 3-1 after 48 minutes. Joe Allen's deflected volley with 10 minutes left gave Liverpool hope but, despite relentless pressure, it could not find another with Steven Gerrard rattling the crossbar from long range. Goals from Luke Varney and Ross McCormack put second-tier Leeds, Cup winner in 1972, in control against Spurs with Clint Dempsey's header not enough to save the Londoners. Much-maligned Spanish striker Torres swept home on 83 minutes to secure a replay for Chelsea at Stamford Bridge. Having missed out on one Wembley appearance after losing over two legs to Swansea City in the Capital One (League) Cup semifinals, Chelsea twice needed to come from behind at Griffin Park. After becoming the first Champions League holder to exit at the group stage and 11 points off top spot in the Premier League, Chelsea's path to silverware this season rests with the Europa League or with the FA Cup, a trophy it has lifted in four of the last six seasons. Trailing 2-1 when Harry Forrester slotted in from the penalty spot with 17 minutes left, Torres kept the Cup holder in the competition. — Agencies
