Almost a fifth for Barcelona as Anthony Gordon tees up Marc Bernal but his effort is blocked in a crowded penalty box.

Feyenoord have mounted a few chances this second half but they have been caught out by the offside flag numerous times.

Fermin Lopez looks to get involved straight away with a powerful strike but Tjark Ernst makes a really good save.

Raphinha is replaced by Fermin Lopez and the Brazilian gets a big hug off Hansi Flick as he makes way.

Deserves that.

Ooooh, Viking living life on the edge but somehow manage to play themselves out of trouble in their own penalty box.

It's been a more defensive display from Stuttgart in this second half and Viking started well but the Norwegians seem to be being pegged back again.

Barcelona make some changes, too.

Anthony Gordon and Marc Bernal come on.

Karim Adeyemi and Pedri make way.

On comes Shaqueel van Persie to replace Nacho Ferri.

Yes, that is the son of Robin.

VAR has a good long look at it and it's ruled out for offside.

It looked close but it Gjivai Zechiel who was off in the build up.

Woah woah. It's kicking off a bit in Stuttgart.

Referee Nenad Minakovic immediately brandishes a yellow card to Joe Bell for a shirt tug and it just starts to spill over.

Nacho Ferri has the ball in the back of the net but it won't count.

He wriggles free and beats goalkeeper Joan Garcia, who should have perhaps done better at smothering the ball, before finishing into an open goal.

But he was miles offside.

Raphinha picks the ball up in the box and tries the little dummy that saw him bag the first goal but this time he runs into traffic.

Peter Christiansen goes into the book for a cheeky flicked foot on Bilal El Khannouss.

What a start to the second half this has been for Viking. Peter Christiansen dives for Henrik Bjordal's ball but his header is just all-out power and no direction and it flings off target.

Lamine Yamal has the ball in the box but he's swarmed by blue Feyenoord shirts every time he gets in those areas.

No magic footwork to get him out of trouble on this occasion.

Karim Adeyemi fancies a second goal and he's looking for a similar thing to his first goal but he doesn't get enough bend on it and it flies wide of the post.
