Crystal Palace 1-2 Southampton
And now the chant from the away end is to question the ability of Palace in the face of the fact that Southampton are winning away from home*.

Oliver Skipp should score, it's quite simple.
I thought there was a possible offside but he needs to show a bit more composure, go with the sidefoot. He just lashes at the ball and blazes over the bar.
Tottenham 1-0 Portsmouth
Huge chance for Oliver Skipp to double the advantage, but he blasts over from close range.
Gillingham 0-1 Leicester
Jake Turner is having a great game in goal for Gillingham. The keeper is the younger brother of Manchester United's WSL player Millie Turner. He's just made another fine save to frustrate Jamie Vardy.
Adam Armstrong
A gift from Palace!
Vicente Guaita makes a real mess of Joachim Anderson's back pass, dwelling on it to allow Adam Armstrong to close him down. When the kick does come, Armstrong sticks in a boot to divert the ball into his path for a finish into an empty net.
From 1-0 down to 2-1 up. There's life in Southampton yet!
Southampton ahead due to Guaita indecision
Tottenham 1-0 Portsmouth
Here's the Harry Kane goal that put Tottenham ahead. Great strike.

Gillingham 0-1 Leicester
Kelechi Iheanacho is Mr FA Cup.
Sixteen goals in the competition for Manchester City and Leicester.
And he's still only 26.
Crystal Palace 1-1 Southampton
Save!
Saints are giving this a go now!
Ainsley Maitland-Nile's cross is flicked on by Adam Armstrong and his effort is drifting towards the far corner of the goal until Vicente Guaita sticks out a hand on the dive to push it away.
Tottenham 1-0 Portsmouth
Japhet Tanganga just throws Colby Bishop to the ground and concedes a free-kick on the halfway line rather than risk losing out in an aerial battle.
Portsmouth are doing their best to try and get out, but referee Thomas Bramall ignores Owen Dale's claims for a free-kick after he's brought down by Ben Davies as he threatened to break away on the right.
Crystal Palace 1-1 Southampton
Oh, almost an opening worked by Saints.
Some neat passing is so close to giving Romain Perraud a shooting opportunity from an angle, but he can't quite control the ball inside the box.
Four minutes after going behind and Preston are level.
It's a great cross in from former Liverpool midfielder Ben Woodburn whose ball is headed into his own net by Huddersfield defender Tom Lees.
1-1. Game on!
Preston equalise with own goal from Lees
Gillingham 0-1 Leicester
Suddenly, Leicester are playing with so much more confidence.
Kelechi Iheanacho fancies a second goal but this time Jake Turner makes the save.
Jamie Vardy who was unmarked looks unimpressed with his team-mate.
Crystal Palace 1-1 Southampton
Saints have made one change with Sekou Mara providing fresh legs up top for Che Adams.
Now Palace make their first moves from the bench, sending on Jean-Philippe Mateta and Luka Milivojevic for Odsonne Edouard and Cheick Doucoure.

It's not as easy now for Portsmouth to retain possession. Tottenham have increased their energy when out of possession, they're closing the ball a lot quicker.
Portsmouth are finding it much more difficult to get out now [of their own half].
Tottenham 1-0 Portsmouth
Bryan Gil can be great to watch when he gets his head down and has a run at a defender or two. He kickstarts another Tottenham attack, which sees the home side win a free-kick in a central position around 25 yards out.
Son Heung-min fancies it, but that's never troubling Joshua Griffiths.
Gillingham 0-1 Leicester
For the first time Leicester's fans are in good voice in Kent. But there's still a long way to go. Will Gillingham respond to going behind?
We've got a goal in our all-Championship tie with Huddersfield taking the lead at Preston.
Terriers forward Florian Kamberi fires past the keeper from six yards out. Are the side in the second-tier's relegation zone on for a mini upset?
Elsewhere in the FA Cup's non-Premier League ties, Watford are still trailing 1-0 to Reading.
Kamberi 'swings it in' to put Huddersfield ahead

It was scrappy and it bobbles but it was Iheanacho, the predator, in the box, ready to take advantage.Gillingham have done so much right.
Turner makes a good save, he had to rely on his defence to mop up everything else. It's a sweet strike from Iheanacho and this will be a test for Gillingham. What is their reaction now?
Gillingham have to stay organised and gamble at some point.

Ex-Liverpool midfielder on BBC Radio 5 Live
Another good ball in from Leicester. Tielemans had a couple of yards to work the cross and Leicester had the overload.
There was no danger Iheanacho was missing from there. Leicester have the lead, now they can relax.
