Exeter have the put in at the scrum, which Toulouse prop Dorian Aldegheri is found guilty of collapsing, and now there's a chance to gain some ground.

Toulouse soon have it back from the line-out, though, and are haring towards the Exeter line again, until Romain Ntamack knocks on.

Toulouse passing at speed again - they're so good in possession. There's another opening here until Juan-Cruz Mallia knocks on, and Exeter can draw breath.

Matthis Lebel on a break, and although Romain Ntamack is held up, Toulouse maintain the momentum - the ball is switched across from right to left and it's looking dangerous, but Stu Townsend does brilliantly to win the turnover, and that gives the home fans a lift.

Stu Townsend works the ball left for Josh Hodge, and there's promise for Exeter - but Toulouse are so good at closing off the space.

Exeter give away a couple of scrum penalties, and Romain Ntamack has kicked towards the corner. From the line-out, the ball is worked right, and Ntamack tries the diagonal kick for the corner, but it's just too far ahead of Juan-Cruz Mallia.

That was absolutely brilliant rugby from Toulouse to score the first try through Dupont.

It's what we've come to expect from this side who have played in Europe so many times, and won the competition half a dozen times.

Every player ran on to the ball at pace. That's the secret of passing the ball, you've got to put it in front of a player.

Josh Hodge kicks for the corner as Exeter respond. Juan-Cruz Mallia runs into touch, but is then penalised for throwing the ball away. Exeter can't capitalise, though, as Francois Cros effects the turnover near his own line.

Henry Slade's kick charged down inside his own 22, but Exeter win it back, and the danger is cleared. Fascinating opening exchanges these.

Matthis Lebel on a surge down the left for Toulouse, and the crowd holds its breath, but Immanuel Feyi-Waboso is across with an excellent chop tackle to put him into touch, and is greeted with cheers.

Positive start from Exeter: Ross Vintcent makes metres, Josh Hodge runs at Toulouse's defence too, but then there's a turnover and the ball is cleared.

England centre Henry Slade playing at fly-half tonight - it has been a problem position for Exeter this season: Harvey Skinner and Will Haydon-Wood have both been used in that role, but neither has made the number 10 jersey their own.

Clean take from Alexandre Roumat, and Antoine Dupont and Romain Ntamack clear.

Henry Slade's boot gets the game going. Exeter in pink, Toulouse in white.

Rugby union has been paying its respects to the late Tom Voyce this weekend. We've a moment's silence before kick-off here.

The two teams go through their final huddles and speeches in their dressing rooms, and are on their way out to join us.

Exeter - Champions Cup winners themselves five seasons ago - opened up their campaign with a 39-21 defeat by Sharks in Durban. It was a bit of an odd finish - Sharks were down to 12 players for about six minutes in the closing stages after having three players sin-binned, but Exeter failed to capitalise.

Before we kick off, a look at how the Champions Cup has been for both teams so far. Toulouse began the defence of the trophy more or less as expected last Sunday: Nine tries, 60-plus points, Ulster well beaten. The expectation is that they will thrive again in this season's competition - a third European title in five years is a strong possibility.

Strong words there from Rob Baxter - it's been a tough season for him and his team so far, but it's obvious from his pre-match interview that he's not losing heart. The words his players need to hear, I suspect.

Exeter director of rugby Rob Baxter, speaking to Premier Sports: "I think we feel like we have a lot of good things in place. We do think we're getting there. Today, if we got a positive result, that would be a huge step forwards; I could really feel things taking off.

"We're not looking to hang in there. We're looking to play to win. If we don't go out there and try to dictate terms, we're not going to learn anything. Whatever happens today, we have to try to be better side afterwards."
