Jalibert sticks it into the corner. Momentum is building.

Jalibert kicks is straight into the arms of Lowry but play is brought back for a penalty after Tom O'Toole went wandering at the maul.

Lucu is having a blinder here.

The 50/22 looks on and he chips it over the top and into touch. Judged to perfection and the hosts have a good platform here.

Joey Carbery can't continue.

Bordeaux have Matthieu Jalibert on in his place. That's ridiculous strength in depth.

Nice and easy from the home captain.

With Carbery receiving treatment, Maxime Lucu points to the posts.

Here come Bordeaux once again.

Maxime Lucu, possibly the smallest man on the pitch, looks to squirm his way into the 22 and he's caught high.

Joey Carbery is also down after being on the end of a big hit.

Penalty for the hosts.

Ulster are almost in after Michael Lowry races through but it's knocked back by Damian Penaud, and that stops Stockdale getting his hands on the ball.

Luke Pearce calls play on, and then Ulster give away a penalty as Moore went off his feet at the ruck.

Right, we're 40 minutes away from finding out who will face Munster in the quarter-finals.

Will Bordeaux finish this one off or can Ulster complete the mother of all comebacks?

Damian Penaud is just a freak of an athlete. He just glides across the pitch and can do everything.

Had they gone in at 21-14 behind at half time, you feel Ulster would have been buoyed.

The concede like they did, after having the ball with just 20 seconds of the half left, will feel like a hammer blow.

It's a credit to Ulster that they recovered from that start but you sense the hosts just moved up the gears again having been dragged back into a game.

They've got to just keep fighting. The scoreline probably reflects the game, some of the offloads have been incredible.

Just a reminder that Bordeaux are being this clinical without Louis Bielle-Biarrey, who is getting a rest after his player of the tournament showing in the Six Nations.

Bordeaux just seem like when they want to score, they can.

After 20 minutes we were panicking, but they started playing really well after that. We thought 'here we go', but they scored right at the end. To have conceded that late is a blow.

Mood.

With the score at 21-0 after 21 minutes, few would have expected Ulster to make a game of it.

Tom O'Toole and David McCann got Ulster back into the game, but the hosts showed their ruthless edge with the final score of the half.

Ulster had battled their way back into it, but Bordeaux have the final say in the first half.
