Premier League leaders Arsenal survived an early scare to come from behind and beat Portsmouth 4-1 at Fratton Park on Sunday in the third round of the FA Cup.
Gunners manager Mikel Arteta made wholesale changes for this clash, expecting a relatively straightforward victory after their 0-0 draw with Liverpool in midweek.
However, when John Mousinho's side took the lead within three minutes - courtesy of Colby Bishop - it seemed as though that expectation was misplaced, but an own goal from Andre Dozzell moments later snuffed out the hosts' spark.
Visiting winger Gabriel Martinelli soon followed up by putting Arsenal ahead with yet another header from a corner, but Pompey remained hopeful after Noni Madueke missed a penalty late in the first half.
Unfortunately for the Championship club, Martinelli doubled the Londoners' lead shortly after the restart, getting on the end of a great cross from Gabriel Jesus after a quick free kick set the former Manchester City man away on the right flank.
Yet another corner led to a simple fourth for Arsenal, and third for the Gunners' number 11, sealing Arteta's side's place in the fourth round with a comfortable win on the road.
SPORTS MOLE'S VERDICT
Portsmouth will be kicking themselves that they were only able to hold onto the lead for five minutes, not to mention that the equaliser was self-inflicted.
To make matters worse, all of Arsenal's goals came from set-pieces that boss Mousinho is sure to be analysing to correct Pompey's errors.
As for the Gunners, they will be pleased that their set-pieces continue to be effective, with three corners and a quick free kick leading to the visitors' four goals on Sunday.
Individually, Martinelli conjured his first hat-trick for Arsenal to turn the game on its head, and the winger will be hoping that his performance can garner positive attention following his headline-grabbing, unsavoury behaviour towards Conor Bradley in midweek.

Madueke's stuttered run-up catches Bursik out, but while the forward sends the shot-stopper to the left, he also sends the ball wide of the right-hand post.

Madueke dribbles infield and is fouled by Chaplin. While Portsmouth are expecting a long free kick to be launched into the box, Arsenal take it quickly, playing the ball out to Jesus on the right wing.
The Gunners' number nine then delivers a brilliant cross along the ground for Martinelli to tap in at the back post.

MAN OF THE MATCH - GABRIEL MARTINELLI
The Arsenal winger has registered just one goal in the Premier League this term, but he was the difference maker against Portsmouth, netting three times that tally on Sunday.
Martinelli headed home two Madueke corners and finished off a fine cross from Jesus to seal the Gunners' spot in the fourth round.
