Good evening and welcome to Eurosport's LIVE coverage of the Champions League group game between Borussia Dortmund and Atletico Madrid. We'll bring you all the action as it happens. Kick off is at 8pm.

Saul has taken a grip of this game in the second half for Atletico Madrid. He carries such a goal threat from midfield, as we have seen in the opening few minutes of this second period.

The bar is still rattling! Inches away from an equaliser for Atleti! Saul whipped the effort from 20 yards out, he beats Burki, but it comes back off the woodwork and bounces away.

Saul past the post! That wasn't far away from the Spanish international. He took the ball on his chest and set up the shot from the edge of the box, but he dragged it wide.

Simeone has already got a reaction from his players. Atletico Madrid have started the second half on top and they are getting more bodies forward on the attack. They're pressing.

It's not surprising that Simeone made a change at the break, but it's somewhat surprising that Lemar wasn't the one who was hooked. The Frenchman has been rather poor.

Simeone has made a change to his team at the break, with Rodri coming on for Partey.

The second half is under way! Borussia Dortmund have a 1-0 lead over Atletico Madrid.

What did you make of the first half at the Westfalenstadion? Does Simeone need to make changes to his side? Are Dortmund on course for three points? Tweet me!

HALF TIME: Borussia Dortmund 1-0 Atletico Madrid. The Bundesliga table-toppers deserve to be ahead at the half time break. Witsel's strike is the difference between the two sides.

Lemar is shown a yellow card for catching Piszczek with his studs in the tackle.

Atletico Madrid are holding on a bit now. The goal has put some real wind into the sails of the home side. They want a second goal before the half time whistle blows.

Zagadou header! Close to being a second goal for Borussia Dortmund. Zagadou was up from the back for a corner, got on the end of the delivery, but powered a header wide of the post.

It's Borussia Dortmund who are pressing for a second goal, rather than Atletico Madrid pressing for an equaliser, towards the end of the first half. They are well on top at the moment.

The pass into Witsel for the goal came from Achraf on the left side. The on loan Real Madrid full back has been one of the best players on the pitch in this first half.

What sort of reaction will we get from Atletico Madrid now? Will they come out and chase the game a little bit more? They have five minutes to equalise before the half time break.

GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOAL! Borussia Dortmund 1 (38 mins - Axel Witsel). Atletico Madrid 0. Dortmund have scored the opener and it's Witsel! The Belgian took the shot from about 20 yards, it picked up a big deflection off Lucas and Oblak is wrong-footed. The ball dribbled past him and the hosts have the lead.
