Adam: Giroud with Messi-like feet and agility there to score, not an easy one that. Great decision from Conte to play him and brilliant signing as well. Now that Southampton have to attack we can counter with the pace of Willian and co. too.

Alawode: Composure personified = Girouuuuuud.

Dave: Shades of Ricky Villa from Giroud!

Donald: Great determination and dribbling by Giroud. He's that special Southampton customer. Impressive record against them.

Olivier Giroud thought about taking his shirt off to celebrate that goal. He decided against it in the end and saved himself a booking.

Giroud is the FA Cup specialist.

I thought he took too long but he was superbly composed.

Wonderful feet, wonderful awareness and composure, goes past three defenders and the goalkeepers and prodded it to an empty net. That is what the game needed.

Off we go.

A reminder there will be extra time and penalties if the teams cannot be separated.

Trust me...it's a better game than the stats suggest.

The teams are out for the second half. I'd love to have listened to Mark Hughes' team talk.

From a Southampton point of view very much job done, getting in at half-time intact.

Antonio Conte will be disappointed Chelsea haven't created too many clear-cut chances.

In the second half you just feel in has to open up.

You can now rate the players.

Willian currently leads the way for Chelsea, while Cedric Soares is a popular choice for Southampton.

Agree? Rate them here.

Southampton's last ditch defending has been good, they have been spirited defending the box, they just can't get out.

Conor: If we don't win today I genuinely don't see a reason for keeping Conte the rest of the season. Sacked in the morning if it's the wrong result

Mission accomplished by Southampton.

They make it to half-time without conceding!

For all Chelsea's attacking play, there's been one shot on target all game...and it's come from Southampton!

Sudan: Longer the game goes on saints fans could feel they can nick this

Olivier Giroud attempts an outrageous overhead kick.

It's wide.

Then Eden Hazard lets fly...it's charged down.

Will Southampton make it to half-time without conceding?

The television camera cuts to Antonio Conte. The Italian is prowling the touchline screaming instructions but he's wasting his time. No one can hear a thing, it's that noisy.

A nice little spell for Southampton but they're struggling to create an opening.

They can't keep the ball long enough to cause Chelsea problems.

Antonio Conte will be reasonably happy with the way it's gone but his side need a goal.

Frustration for Chelsea!

A corner by Willian is flicked on by Cesar Azpilicueta across the six-yard area but there are no blue shirts to divert it over the line.

David: I think Saints fans might just have had enough of football this season, FA Cup semi-final or not. You need to watch the team week-in, week-out.

Chelsea are prodding and probing in and around the Southampton penalty area.

Olivier Giroud hooks wide on the volley after Eden Hazard bursts into the box.

It's backs-to-the-wall stuff from the Saints.
