Leinster have started with seven players who began Ireland's 40-10 Six Nations clinching win over Scotland two weeks ago. But they have yet to settle. Bath on the attack, throwing the ball around just outside the home 22, but a pass wide from Kyle Eastmond goes into touch.

Clever run by Anthony Watson as he takes the high ball. Bath are up for this. Leinster counterattack down the left wing, but it's a forward pass, giving the put-in at the scrum to Bath.

Bath win the first line-out and George Ford is immediately in the centre of the action with a clever kick to the corner.

And we're under way.

Blue Leinster flags everywhere. We're ready for the off...

Terrific noise in the Aviva Stadium. Here come the teams...

Bath Rugby:, external Huge cheers as the Bath team is announced across the stadium. Excellent travelling support here in Dublin.

Bath director of rugby Mike Ford tells BBC Radio Bristol: "We're really looking forward to today. The boys have been so excited this week, I've had to calm them down a little bit. But we've prepared really well on the whole. I just want us to impose ourselves with the ball in hand."

Graeme Hobbs:, external Think Bath or Northampton have the best chance of winning #EPCRChampionsCup they have been the most impressive of English teams.

Dominic:, external If Bath's backline fires then they can beat anyone on their day. Ford has to be on song if they are to stand a chance though.

Dean Osborn:, external Leinster all the way and with some to spare.

Leinster: Rob Kearney, Fergus McFadden, Ben Te'o, Ian Madigan, Luke Fitzgerald, Jimmy Gopperth, Isaac Boss; Cian Healy, Sean Cronin, Mike Ross, Devin Toner, Mike McCarthy, Jordi Murphy, Sean O'Brien, Jamie Heaslip.

Replacements: Richardt Strauss, Jack McGrath, Martin Moore, Tom Denton, Dominic Ryan, Eoin Reddan, Gordon D'Arcy, Zane Kirchner.

Bath: Anthony Watson, Horacio Agulla, Jonathan Joseph, Kyle Eastmond, Matt Banahan, George Ford, Micky Young; Paul James, Rob Webber, Kane Palma-Newport, Stuart Hooper, Dave Attwood, Carl Fearns, Francois Louw, Leroy Houston.

Replacements: Ross Batty, Nick Auterac, Max Lahiff, Matt Garvey, Alafoti Faosiliva, Peter Stringer, Sam Burgess, Tom Homer.

Leinster are boosted by the return of their Six Nations-winning Ireland players. The hosts make nine changes with captain Jamie Heaslip, Sean O'Brien and Rob Kearney among those brought in.

Bath welcome back five internationals including England quartet George Ford, Jonathan Joseph, Anthony Watson and Dave Attwood. Wales prop Paul James is back after recovering from a thumb injury.

Fifteen minutes to kick-off and fans are pouring into the Aviva Stadium. It's a lovely spring day in Dublin. Team news coming up.

First-team coach Toby Booth is under no illusions about the task that awaits Bath in Dublin. "Leinster are a very, very dangerous," former London Irish head coach Booth, 45, tells BBC Radio Bristol.

"They've rested a lot of players from the Irish team this week, so they'll be massively bolstered. I think having [Irish international flanker] Sean O'Brien back and people like that - it's going be a tough contest and we know how good we've got to be."

Will Bath fly-half George Ford purr like the engine of a Ferrari at the Aviva Stadium or run out of petrol on his return to Ireland?

The 22-year-old was part of the England side defeated 19-9 by Ireland in Dublin last month and Ford believes that experience will help him against Leinster.

"Leinster have internationals from one to 15," Ford said. "The quality of their players is far superior to what we are used to, and we will have to be top of our game to get a result."

Will a club from England be celebrating at Twickenham on 2 May?

Peter Quinlan: Not a chance, two French teams. Northampton's chances went with North's injury.

Joshua Daniel Jones: Northampton...maybe.

Bath are not be short of support in Dublin. Hundreds have crossed the Irish Sea to back Mike Ford's team including these six from the old Roman spa city.

Twickenham is the stage for this season's final on 2 May - and that's a good omen for Leinster.

The last time the Dublin-based club were crowned European champions was 2012 - when the final was at Twickenham.

Leinster have defeated Wasps and Harlequins in Ireland this season on their way to finishing top of Pool 2. Can they make it a hat-trick of wins over English clubs?
