A monstrous Stade scrum overpowers Ulster on their own 22. Their handling lets them down again but they had an advantage coming so Zack Henry nudges into the corner.

Paul Gustard introduces his own bomb squad five minutes into the second half with five subs thrown on at once.

Dave McCann tries a rather ill-advised offload which is picked up by Yoan Tanga. The big No. 8 kicks on but it is well recovered by Robert Baloucoune.

Yours truly played in the back row back in the day (whenever I was fitter!) and would have been very pleased with an open play kick like that!

Here we go for the second half with Ulster kicking off towards the War Memorial End.

I've no doubt Zac Ward is a name Andy Farrell [Ireland coach] will be thinking about, especially with the way he carries the ball.

He carries the ball with venom - it takes two or three players to take him down.

It's been a really impressive performance from Ulster - it's been a mature and composed display.

All 15 players have bought in to what they have to do today.

A scintillating first 40 for Ritchie Murphy's men sees them claim the bonus point and keep the visitors with a bagel on the scoreboard. Does that technically count as 120 minutes of scoreless rugby?

You couldn't have asked for much more than that though from a first half at the Affidea Stadium.

Zack Henry makes ground through the gap but his pass to HIA replacement Samuel Ezeala hits the deck. Scrum down Ulster but Stade claim it came off Zac Ward's hand and they may have had a point!

Ulster infringe at the ruck and Zack Henry sends the ball towards the 22. Can the visitors get anything on the board before the break?

Ulster are performing really well today - a couple of things we want to clean up but the workrate and accuracy has been really impressive.

Just a reminder for all the permutation fans out there, with their four-try bonus point secured, Ulster just need to now focus on winning the game to be sure of topping the pool.

Even in the unlikely event that Stade were to claim two bonus points in defeat from this position, Ulster would still edge ahead in the standings with a win.

Ten minutes until the half and Jack Murphy puts a penalty into the corner, Stade were making some big dominant tackles but just strayed offside.

Ulster's lineout throw is over the top and the Parisians can clear.

The try is disallowed as Robert Baloucoune's final pass to Nathan Doak is forward. It was more brilliant rugby from Ulster but the final pass just let them down.

Stade's pack have been strong despite the early Ulster pressure. They steal an UIster lineout inside the 22 and Giorgi Melikidze puts his head down and goes for the line.

It takes a swarm of white shirts but Ulster hold up the Georgian monster over the line.

Stuart McCloskey has been everywhere in the opening thirteen minutes. He gets on the end of a Jack Murphy cross-field kick and bounces off the tackle of Charles Laloi.

Again, the hosts move coast to coast and Robert Baloucoune stretches his powerful legs but his offload to Jacob Stockdale doesn't stick. However, Stade are feeling generous and they gift Ulster the ball back.

McCloskey is the target again for a cross-field kick but it's just a step ahead of him. This has been a furious opening to this one.

Stade make good ground up the middle but another loose pass comes off the knee of openside Mathieu Hirigoyen and Ulster clear putting the visitors on the back foot.

Stade threaten out wide through Charles Laloi but they give the ball away and Stuart McCloskey launches a kick into no-man's land out the back which dribbles out just shy of the 22.
