When Portsmouth were on top in the first half, they they needed to score. They didn't take their chances and that was the difference.

The first goal killed them. It deflated a good performance.

Arsenal started well in the second half and completely dominated the game. They were patient and turned out to be comfortable winners.

Arsenal are the first team into the FA Cup quarter-finals.

Steve Seddon stands over it and whips in a wicked left-foot inswinger... but it is too strong. That should be that.

Former Arsenal academy kid Christian Burgess is named Pompey's MOTM. Small consolation.

Another would be if they grab a late goal. Free-kick on the right...

Arsenal run the clock down a little more - firstly by taking off Reiss Nelson, and then as they try to hold the ball in the corner when play restarts.

Let's get this wrapped up then. Just the three minutes of stoppage time.

Easy night's work for Emiliano Martinez, in truth. That will disappoint Kenny Jackett, that his side haven't been able to test the Gunners keeper more. John Marquis tamely crosses straight into Martinez's hands from the right.

Portsmouth were unlucky to be behind at half-time. But Arsenal have dominated the second half and have been the better team.

Here comes Granit Xhaka for the final minutes. That appearance bonus will boost his pay packet at the end of the month. Joe Willock, one of a number of good performers today, trudges off.

An Arsenal change is imminent. To slow time and momentum, of course.

Can't fault Pompey's endeavour. Substitute Andy Cannon fires one goalwards... but it is not straight and goes wide.

Back up the other end, Arsenal look to call this one off. Alex Bass in the Pompey goal gets down to smother a shot.

Not yet... Ronan Curtis crosses in from the left, no danger.

Arsenal not the only ones singing, Pompey's fans haven't stopped. Reckon they'd cheer a home goal now like one which get the promoted...

Arsenal utterly dominant this half. Still they continue to sing in possession, still Matteo Guendouzi conducts.

Over 80% of possession for the Gunners since the break.

Luke: Why all the talk about bigger games for Portsmouth? If Arsenal win their game in hand they are level with Spurs, and only two points behind United in chase for Europe. Six U20 for Arsenal shows where their priorities lie as well.

A third is coming. Can feel it.

Not for the first time, Bukayo Saka has been impressive. The Arsenal left-back has the Pompey defence on strings, finding space to drill a rising shot goalwards. Pompey keeper Alex Bass tips over to be sure.

Last rummage in the tactical hat for Kenny Jackett. Is Andy Cannon the rabbit he needs? He is on for skipper Gareth Evans.
