Toulouse win a penalty at the scrum! Jeremy Loughman is the one pinged by referee Luke Pearce!

The chance slips away for Munster.

Five minutes to find a winner before we head to the place-kick shoot-out.

Ben Healy snaps a drop-goal attempt! It...is....wide.

But we are coming back for a Toulouse offside offence.

Munster with put-in to a scrum bang central, 20m out from the Toulouse line.

Massive chance here.

A mighty turnover from Jack O'Donoghue to stick a spanner in the Toulouse gears as the visitors attempt to build around halfway.

A kick up to the Toulouse 22m. Munster to throw into the line-out...

Dublin is absolutely rocking and both teams waiting for kick-off in Leicester may be hoping their side can wrap it up in 80 minutes!

Here is what the two coaches have had to say ahead of the clash.

Leicester head coach Steve Borthwick: "Leinster are a very good side, with world-class players throughout their squad who have a great understanding of one another and the way they play.

"This is a group that have been together a long time, played a lot of rugby together for Leinster and, most of them, at international level with Ireland.

"It will be an incredible challenge, but what a great opportunity for us against a team of their quality and what a great test."

Leinster senior coach Stuart Lancaster: "Leicester are probably international quality in every position in my opinion. It's not dissimilar from our team. They have got a lot of experienced players. It's going to be one of the special European games for sure."

The red-clad wall of noise reaches new levels as the players are summoned for the second half of extra time.

Here we go.

Toulouse rev up the driving maul and make some big metres towards the Munster 22m. But then it goes down and here comes the counter-ruck!

Massive cheers from the stands!

The Cranberries' Zombie booms out of the stadium tannoy as the teams take on the final instructions.

A place-kicking competition will follow if the two teams still cannot be split.

Ben Healy boots us off in the first period of extra time.

They have got their money's worth from this trip to the Aviva.

So, it is 10 minutes each way.

If the teams still can't be split, it will go to tries scored, which is currently three each.

And then we could have a place-kicking contest if the two are still locked together.

It's long, it's long, but it's not quite long enough.

The ball drops short and a little wide and we are heading into extra time.

What!?

Penalty to Munster, 10 metres inside their own half.

And Ben Healy, boot like a bazooka, has called for the tee.

This for the win from way downtown....

We are heading for extra time as it stands.

The margins are so thin!

Antoine Dupont rifles a grubber kick for the corner and is only half a yard the wrong side of the corner flag.

He claims it caught a deflection off a Munster foot on the way. The video replay is not clear.

We go back for a Munster scrum from where it left Dupont's foot.

Three to go.

Argh!

A potentially costly error from 22-year-old lock Thomas Ahern as he takes out Thomas Ramos in the air off the kick-off.

Toulouse kick for touch in the Munster half and will throw into the resulting line-out.

Over it goes.

Drama distilled to 100% proof.

Four to go.

Penalty Toulouse!

The Munster pack was crumpled like a car-wreck bonnet.

Luke Pearce points skywards. Thomas Ramos calls for the tee.

Cyril Baille drops it! It's forward. The France prop was ambushed as John Ryan rushes up on the fringe and catches him unawares.

Scrum red, 15m from their own line...

Some huge hits coming in from Munster. Still Toulouse retain the ball and keep pouring forward.
