Needs must.

Off goes full-back Nathan Byrne and on comes 35-year-old striker Noel Hunt for the hosts.

Anon: Best game of the quarter finals by far.

Dean: I want extra time forget about question of sport!!!

Ryan Colclough cuts the ball back into a prime piece of penalty area...but there is no-one there for Wigan.

The Latics are piling forward. Southampton are pretty much shutting up shop.

This ain't over yet.

David: This Wigan keeper is top draw, big save!

Caley: What a brilliant save by Walton!!!

James: Walton for England?

Wigan are being roared into attack by the DW Stadium crowd.

They have a corner....

Any touch? Any! None.

The ball just eludes Nick Powell at the back post.

Southampton could have gone two up from the penalty spot.

But as it stands Højbjerg's goal is the difference between the two sides.

Often you see penalty saves and think the are pretty good. That was absolutely off the scale. How brilliant was that? He flung himself to his left to stop that. One of the best saves I have seen in years.

The hairs are up on the back of my neck because that is just a wonderful save. Outstanding! That was incredible wasn't it?

Brilliant!

Christian Walton plunges to his left and palms Manolo Gabbiadini's rocket spot-kick round the post.

An astonishing save. He must have wrists of titanium.

Manolo Gabbiadini gets the wrong side of Dan Burn and the Wigan centre-back brings down the striker as he slides in to try and recover the situation.

Yellow and a spot-kick...

You can't help put think that Wigan might have to get some more help up to Will Grigg. He can fight and battle and score on his own, but if they are to find a route back into the game he needs more support.

This is going to be a helter-skelter last 20 minutes.

Wigan are pressing forward. They are not going to die wondering. And why should they? They have been the better side for most of this match.

Southampton have the quality to exploit space on the break as well.

Nick: Thoroughly undeserved but has been coming. Hope Wigan can get the equaliser that they deserve - it suspect a sucker punch second at some time.

Samuel: Wigan should be at least 2-0 up before that goal. There going to be disappointed with those missed chances. Can't see Wigan getting back into this now.

You almost do not recognise them from the first half. Southampton deserve that goal, they have created some good chances and played super football in the second half.

Well done Mark Hughes for changing it.

It is a massive goal from Southampton. Wigan just went to sleep. How it finds its way into the back of the net from there is unbelievable. It just creeps through a group of players! You have to give Pierre-Emile Hojbjerg credit there.

Southampton have just gone ahead, after some heavy pressure.

But earlier Wigan had the first meaningful effort of the second half through Michael Jacobs.

Both managers shuffle the pack in the wake of that opening goal.

Mark Hughes takes off the ineffectual Sofiane Boufal and slings the energy of Nathan Redmond into the mix.

Paul Cook who ruled Nick Powell out of the match with a dodgy hamstring earlier in the week, has put the former Manchester United man on in play of Gavin Massey.

Ryan Colclough is on in place of Gary Roberts as well.

Southampton are showing more ambition in the second half.

Pierre-Emile Hojbjerg bullets a header goalwards which is turned over the top smartly by Christian Walton.
