Bath scrum-half Ben Spencer has put boot to ball a few times already - good tactics on a filthy evening like this - and that's his most effective so far as Munster are pinned down near their line.

Bath are on the charge.

The rain really is teeming down at The Rec tonight but it certainly hasn't dampened the atmosphere with the fans in full voice.

Bath fans will be used to watching their team in the rain with no roof on half the stands!

It is wet and windy in the West Country!

How will that effect tonight's action?

Let's find out shall we...

Italian referee Gianluca Gnecchi blows his whistle and Bristol fly-half Sam Worsley gets us under way in Llanelli.

Scarlets in all white this evening.

Bath: De Glanville; Cokanasiga, Ojomoh, Redpath, Arundell; Russell, Spencer; Obano, Dunn, Stuart, Roux, Ewels, Bayliss, Pepper, Reid.

Replacements: Tuipulotu, Van Wyk, Du Toit, Molony, Hill, Carr-Smith, Carreras, Underhill.

Finn Russell makes his 50th appearance for Prem champions Bath as they set their sights on a first Champions Cup trophy since 1998.

The one-time winners will certainly aim to better their disappointing group-stage exit last season and have named a strong side captained by Ben Spencer for the sell-out game at the Rec.

Beno Obano, Tom Dunn and Will Stuart start in the front row with England's Guy Pepper returning to the starting line-up at open-side flanker.

Cam Redpath and Max Ojomoh form the centre partnership with Henry Arundell and Joe Cokanasiga on the wings and Tom de Glanville at full-back.

Ted Hill, Sam Underhill and Santi Carreras are among the replacements.

Munster are without fly-half Jack Crowley who has been ruled out with a leg injury as head coach Clayton McMillan makes five changes from the side that lost to the Stormers last weekend.

Ex-Leinster prop Michael Ala'alatoa is set for his Munster debut off the bench, while JJ Hanrahan comes in to replace Crowley and partners Craig Casey in the half-backs.

Captain Tadhg Beirne, John Hodnett and Gavin Coombes are in the back row.

Louis Rees-Zammit was impressive in Wales’ spirited performance against New Zealand in the third of their autumn internationals, diving over acrobatically for the fourth try.

He was on Bristol’s bench for the 46-12 thrashing of Northampton in the Prem but slots in on the right wing.

England loose-head prop Ellis Genge also comes into the XV while

Wales Under-20s wing Aidan Boshoff, who scored against Northampton, is poised for a European debut off the bench.

Bristol: Jordan, Rees-Zammit, Van Rensburg, J Williams, Ravouvou; Worsley, Marmion; Genge, Oghre, Lahiff, Rubiolo, Batley, Grondona, Harding (capt), Mata.

Replacements: Thacker, Woolmore, Chawatama, Owen, Grondona, Wolstenholme, Boshoff, Carrington.

Scarlets head into the Champions Cup in high spirits after recording a first win of the season in the United Rugby Championship.

They impressively beat Glasgow 23-0 and head coach Dwayne Peel makes three changes to his XV by bringing Wales internationals Tom Rogers, Johnny Williams and Ellis Mee coming into the back line.

Scarlets are without full-back Blair Murray, who started all four of Wales' autumn internationals, because of a knock. Back-row forward Taine Plumtree misses out with a rib injury suffered against South Africa.

Joe Hawkins and Joe Roberts have to be content with places on the bench after featuring against the Springboks last weekend.

Scarlets: J Davies; Rogers, James, J Williams, Mee; Costelow, G Davies; Mathias, Elias, Holz, Lousi, Ball, Douglas, Macleod (capt), Anderson.

Replacements: Van der Merwe, S O'Connor, H Thomas, Taylor, Davis, Blacker, Hawkins, J Roberts.

We've just seen two English sides suffer defeats on the road, can Bristol avoid the same fate against Scarlets?

The Bears have travelled over the Severn Bridge to Llanelli for what promises to be a cracker.

Scarlets, who host Pau in round three, know that home form is vital given that they have trips to Bordeaux-Begles and Northampton.

Leinster captain Caelan Doris speaking post-match on Viaplay:

“Yeah, maximum points was the big thing for us and getting the bonus-point win as well. Performance-wise, though, we’ll need to improve quite a bit going into Leicester away next week and as we go deeper into the tournament. There were a few moving parts this week. That’s not an excuse, but there’s definitely more in us.”

This bonus point win means that La Rochelle are top of Pool 3 on points difference from Leinster, Leicester will host the Irish side next Friday at 20:00 GMT.

Leinster secure a bonus-point victory over Harlequins in Dublin after pulling clear in the second half. Jordan Larmour crossed twice in a lively first half, with Garry Ringrose and Ciaran Frawley also on the scoresheet as the hosts built their platform. Harlequins stayed in touch with three first-half tries of their own.

Leinster’s depth told after the break as Tommy O’Brien, Jack Conan and Jimmy O’Brien all touched down to stretch the margin. A late breakaway score from Oscar Beard proved a consolation for the visitors but crucially secured Harlequins a four-try bonus point.

That’s it at the Aviva and it’s a convincing Leinster victory in Dublin. The scoreline reflects Leinster's quality, though there were some frustrating moments along the way for Leo Cullen’s side. Harlequins battled bravely for the first hour before Leinster’s depth and power eventually told as they pulled clear.

It's all over as La Rochelle claim the win, but Leicester can take something from a spirited performance against a strong, experienced side.

Just a few minutes to go and it has been a much more clinical final quarter from Leinster after a frustrating start to the half. The hosts are showing no signs of easing off the accelerator as they set up another attacking line-out deep inside the Harlequins half, with the visitors facing the prospect of further pressure.

It's a cruel, harsh end to the game for this young Leicester line-up, but they may well learn from this.
