Tomas Rosicky scored one and set up another as Arsenal held off a second-half rally from Brighton to win 3-2 and book their place in the fifth round of the FA Cup.
Arsenal looked to be cruising to victory at the Amex Stadium after Theo Walcott's opener after 90 seconds and Mesut Ozil's close-range finish put the holders two up at the break.
Brighton, however, twice reduced the advantage to one in the second half as Chris O'Grady and Sam Baldock both found the net either side of Rosicky's superb volley to give the home side hope.
The Seagulls poured forward late on and could have had a penalty when Calum Chambers handled in the box with five minutes to play, but the Gunners were spared and it was the holders who sneaked into the next round.
The home fans had barely taken their seats before Walcott latched onto Chambers' driven cross and fired a low shot into the far corner for his first Arsenal goal since New Year's Day 2014.
In the 24th minute, Arsenal doubled their advantage as Rosicky ghosted inside from the left and as Brighton worked out who should close down the midfielder, he slid in Ozil, who tucked the ball home from close range.
Arsenal cruised into the break relatively untroubled, but four minutes into the second period the contest was sparked into life.
Chambers failed to clear the ball on the edge of the box and O'Grady seized the opportunity, rolling Mathieu Flamini and driving low past Wojciech Szczesny to give his side a lifeline.
Brighton's goal injected belief and tempo into the home side's play and suddenly it was Arsenal who looked rattled.
The Gunners had a penalty appeal when Gordon Greer appeared to handle Giroud's flick before Brighton were crying foul at the other end when Inigo Calderon took a tumble after a tangle of legs in the box with Koscielny.
Just as Brighton looked to be gaining momentum, however, Arsenal struck again.
Rosicky recovered possession outside Brighton's box, beat two players before playing a disguised pass left to Giroud. The striker chipped the ball back into Rosicky's path and the Czech volleyed past David Stockdale to restore the two-goal advantage.
Arsenal tried to establish some control over the tie but Brighton continued to rally and in the 75th minute, they again pegged their opponents back.
Danny Holla collected possession 25 yards out and the midfielder played a beautifully weighted pass into Baldock, who lifted the ball over Szczesny and into the net for 3-2.
Sanchez hit the crossbar with a bending free-kick with six minutes to play but Brightoncame again and could have had a penalty when Adrian Colunga's cross hit the arm of Chambers.
Michael Oliver, however, waved away the appeals and the Gunners held on to book their place in the next round.
Carles Gil helped fire Aston Villa into the FA Cup fifth round as they avoided an upset to beat Bournemouth 2-1.
The midfielder's first goal for the club on his full debut put the hosts ahead against the battling Cherries, who troubled Villa in the first half.
Andi Weimann's second-half strike - his first goal since November - then proved crucial as Villa extended their lead.
Callum Wilson replied deep into stoppage time but the visitors ran out of time to mount a comeback.
Eddie Howe's Sky Bet Championship leaders did scare Villa, though, with Kieran Richardson clearing off the line from Shaun MacDonald and Eunan O'Kane twice going close.
Bournemouth were brighter as Villa struggled to gain momentum against the vibrant Cherries.
O'Kane was denied by Given before he fired over from the edge of the box as Villa hung on and Okore made a fine tackle five minutes before the break as Yann Kermorgant threatened to break through.
Bournemouth were in control, although were unable to find a breakthrough before half-time, but Villa conjured a fine chance just two minutes after the re-start.
Benteke seized on a loose pass and evaded two challenges before Gil collected the ball and fired into the side netting.
However, the Spain Under-21 international did break the deadlock on 51 minutes with a beauty. He collected the ball before cutting inside, easily beating Cook on the right, and curling a wonderful strike into the top corner from 18 yards.
It was Villa's first goal in 223 minutes in all competitions and knocked the stuffing out ofBournemouth.
Wilson and Simon Francis were thrown on but Villa doubled the lead on 71 minutes when Weimann converted Hutton's low cross from 10 yards.
The Cherries did pull a goal back in injury time when Wilson tapped in from close range to end a neat move.
