Gunners come from two-down to see off Villa
Arsenal scored three times in seven second half minutes to overturn a 2-0 deficit and beat Aston Villa 3-2 in the FA Cup fourth round on Sunday.
Robin van Persie netted two penalties and Theo Walcott scored the other to book Arsenal's place in the last-16.
Elsewhere, Manchester United crashed out to rivals Liverpool, while Newcastle fell to Championship side Brighton.
Chelsea overcame neighbours Queens Park Rangers and Tottenham edged past Watford on Friday evening.
Arsenal 2 Aston Villa 3
Richard Dunne gave Villa the lead midway through the first half when he rose highest to nod in Robbie Keane's cross.
Darren Bent doubled the advantage right on half-time, latching onto Stephen Ireland's through ball and sliding home from a tight angle at the second time of asking, after seeing his initial effort parried.
Goalkeeper parries do not remove assists, so Ireland is credited with the two Fantasy League points for his initial pass. It doesn't matter that Bent's first shot was parried because he had already received a complete pass from Ireland so the assist stands as per the last pass to the goalscorer rule.
Nine minutes after the restart Robin van Persie pulled a goal back for Arsenal, slotting home from the penalty spot after Aaron Ramsey had been fouled.
Three minutes later Walcott inadvertently levelled; running onto Thomas Rosicky's pass he saw his shot saved by Villa keeper Shay Given before Alan Hutton cleared the loose ball, which cannoned in off Walcott's head.
Rosicky retains the assist as per the last pass to the goalscorer rule because he had already made a completed pass to Walcott before the winger temporarily lost possession prior to scoring.
Van Persie completed the turn-around on the hour mark with a second penalty after Laurent Koscielny had been tripped.
Bolton 2 Swansea 1
Luke Moore opened the scoring for the visitors when he ran onto a loose ball, which had been prodded into his path by Leroy Lita, and slotted home.
The lead lasted just a minute before Darren Pratley headed in Martin Petrov's free-kick to level matters.
Petrov was the provider again for Bolton's winner, when his shot was parried by the Swansea keeper and Chris Eagles was on hand to turn in the rebound.
Brighton 1 Newcastle 0
The Championship side progressed into the last eight courtesy of a Mike Williamson deflected own goal.
Derby 0 Stoke 2

Huth then scored the second himself when he turned in Jermaine Pennant's corner nine minutes from time.
Everton 2 Fulham 1
Danny Murphy opened the scoring for the visitors on Friday night, sliding in a penalty after a handball by Everton defender Johnny Heitinga.
Denis Stracqualursi headed in Landon Donovan's cross to level the scores, before the American provided the cross for Marouane Fellaini to nod in the winner 17 minutes from time.

Queens Park Rangers 0 Chelsea 1
Juan Mata scored the only goal of the game from the penalty spot after Daniel Sturridge had been pushed.
