Liverpool and Tottenham were knocked out by lower league opponents, as Chelsea survived by the skin of their teeth in a remarkable day of Cupsets in the fourth round of the F.A. Cup.
The oldest tournament in England lived up to its reputation of throwing up crazy results and Oldham Athletic and Leeds United added some history Sunday.
League One side Oldham, who are struggling in their division, two below Liverpool, produced a brilliant all-round performance to get the better of their more illustrious opponents 3-2, with two goals from Matt Smith and one from Reece Wabara consigning the Reds to an embarrassing defeat.
Luis Suarez and Joe Allen got the goals for the away side at Boundary Park, but it was not enough to at least force a replay against an Oldham side that thoroughly deserved the win.
Earlier, Chelsea needed a late goal from Fernando Torres to get themselves a rather fortunate 2-2 draw against League one side Brentford.
In a first half that Chelsea will want to forget rather quickly, Marcelo Trotta gave the home side the lead at Griffin Park, latching onto a rebound after goalkeeper Ross Turnbull, who had a nightmare of a game, had saved an initial effort.
The Blues were lucky not to have been down by more than one goal after the first half, with Brentford taking the game to the European and F.A. Cup champions, and making them look like lower league opposition rather than the other way around.
The second half saw Juan Mata come on for the ineffectual Marko Marin, and that seemed to be just what Chelsea needed as they finally started to play like they are capable of.
Oscar equalized ten minutes into the second half with a wonderfully-taken goal with the outside of his right foot.
However, Brentford again took the lead in the 73rd minute via a penalty after Turnbull brought down substitute Tom Adeyemi, with Harry Forrester stepping up to dispatch the spotkick.
Just when it looked like Brentford were headed to a famous win over their West London neighbors, Torres struck with a brilliant curling effort into the top corner in the 83rd minute to force a replay.
At Elland Road, Spurs fell to Leeds thanks to goals from Luke Varney and Ross McCormack in another great performance from a lower league side against Premier League opponents.
Clint Dempsey reduced the deficit just before the hour, but Spurs just could not find the equalizer as Leeds booked themselves a place in the fifth round.
