Day of Delicious Upsets: Arsenal's primary FA Cup rivals fall

In the previous FA Cup draw, Arsenal had a chance to draw four of its biggest Premier League rivals in Manchester City, Chelsea, Southampton, and Spurs. That won't be the case when the 5th round draw rolls around.

In a day of FA Cup action that this Arsenal fan's just going to go ahead and describe as "delicious," "awesome," and "schadenfreudetastic," the following matches delivered some underdog, on-the-road FA Cup magic:

Middlesbrough 2, Manchester City 0: In a match at the Etihad filled with defensive errors, the Smoggies put in a 53rd-minute goal after an entertaining pinball sequence, and put in an insurance goal in stoppage time to send the Citizens out of the tournament.

Bradford 4, Chelsea 2: After Chelsea went up 2-0 at Stamford Bridge, Bradford put in four goals to step back into the giant-killing role they played a few years back in some match I've totally forgotten. Despite throwing on Cesc Fabregas and Eden Hazard as late-match subs, Chelsea saw Bradford put in an 82nd minute go-ahead goal after tying the match eight minutes prior, and someone named Mark Yeates sealed Chelsea's first home loss of the season in any competition in the 90th minute.

Leicester 2, Spurs 1: Despite going up 1-0 on a 19th-minute Andros Townsend PK, and keeping the Foxes scoreless most of the match, Leonardo Ulloa equalized in the 83rd minute, and then in the 90th minute, someone named Jeffrey Schlupp volleyed in a cross to bounce Spurs in front of their home fans at White Hart Lane.

Crystal Palace 3, Southampton 2: In a match featuring five first-half goals, Arsenal loanee Yaya Sanogo scored, and Arsenal outcast Marouane Chamakh scored twice to lift Palace to a road victory against the Saints.

In earlier upset action today, the floundering Swansea were bounced from the Cup by Blackburn, 3-1, in front of less than 6,000 at the Rovers' stadium. Swansea did go up 1-0 in the 21st minute, but gave up the equalizer two minutes later, and finished the match with just nine men. In possible other upset action today, Emile Heskey's Bolton will travel to Anfield in an attempt to dispatch Liverpool.

Arsenal, of course, plays its 4th round tie at Brighton & Hove Albion tomorrow.
