And La Rochelle get us under way, they are playing into a stiff breeze in the first half.

Gloucester head coach George Skivington, speaking to BT Sport:

"We're not underestimating what's coming. They had a great season last year, have had a great time in this tournament for a couple of years now and they don't lose very often here. The task in front of us is huge but we've prepared well and we'll rip into it."

La Rochelle forwards coach Donnacha Ryan:

"We've got a new group of players this year compared to last year, they're still growing as a group, but we took a lot of confidence from qualifying in the way that we did. In the Champions Cup, you can't underestimate the opposition. Cup rugby brings out the best in players and hopefully today we can see the best in our guys."

Here's the match report from Stormers' win against Harlequins a little earlier today in Cape Town...

Our main focus is on Gloucester's tie in France, but we'll also be keeping an eye on Leinster v Ulster and will bring you regular score updates.

You can listen to radio commentary of both games at the top of this page.

It's blustery out on the French Atlantic coast, but dry. I don't think this will be a penalty-laden grindathon.

Gloucester make three changes to the side narrowly beaten by Newcastle for their Heineken Champions Cup last-16 tie at defending champions La Rochelle.

Billy Twelvetrees starts at fly-half, while Mayco Vivas makes his first club start at prop and academy graduate Jack Clement is named at number eight.

Seb Atkinson signed a new deal with the Premiership club this week and retains his place at inside centre.

Wing Jules Favre will make his 100th appearance for the French side.

Gloucester: Carreras; Rees-Zammit, Harris, Atkinson, Thorley; Twelvetrees, Varney; Vivas, Blake, Gotovtsev, Clarke, Alemanno, Ackermann, Ludlow (c), Clement.

Replacements: Walker, Elrington, Ford-Robinson, Jordan, Thomas, Morgan, Chapman, May.

La Rochelle: Dulin; Thomas, Rhule, Danty, Favre; Hastoy, Kerr-Barlow; Sclavi, Bourgarit, Atonio, Lavault, Skelton, Dillane, Botia, Alldritt (c).

Replacements: Lespiaucq, Wardi, Colombe Reazel, Sazy, Tanga, Boudehent, Berjon, Reus.

Phew! And we go again, for another tasty-looking morsel of Champions Cup action.

The South African side will face the winners of Exeter v Montpellier, which kicks off at 12:30 BST on Sunday.

Stormers forward and player of the match Deon Fourie, speaking to BT Sport:

"Quins are a quality side, we let it slip a bit at the end, but we got the win. In the knockouts if you win by one or by 20, you just have to go through.

"[Our defence] is our foundation, we attack from our defence and I think we did well except for the last 10 minutes. We'll look at the game again afterwards and see where we can improve."

A game with a cracking opening and an entertaining finale comes to an end, but the upshot is that Stormers go through at the expense of a spirited Harlequins.

Credit to the away side for their stickability late on, on a hot and testing afternoon.

There's a scuffle in the Harlequins 22, and from the penalty Manie Libbok kicks to the corner.

Ugo Monye has just informed viewers on BT Sport that Harlequins have had 69% possession - but they have nothing to show for it, telling you how good the Stormers' defence has been.

Agh! Harlequins centre Andre Esterhuizen fumbles the ball with the line at his mercy, then he angrily hoofs it into the stands.

Fair play to Quins, they have spent a few minutes in the opposition's half. Marcus Smith then tries a cute kick but Damian Willemse collects it easily to ease the pressure.

Valiant stuff from Harlequins as they try to bust through the Stormers defence, but there is no way through. Marcus Smith looks disconsolate, it is beginning to look like it won't be their day.
