Viking break and it comes to Kristoffer Askildsen just outside the area. He tries to bend one into the corner but Fabian Bredlow gets across well to make the catch.

The visitors did well to fashion the opportunity but almost looked to have run out of steam by the time it came to having a shot.

Stuttgart are probing but it's very much a wall of Viking shirts in the box at the moment.

Barcelona get forward and it's almost a carbon copy of the opening goal. But this time Lamine Yamal's pass to find Raphinha is a bit behind him and he can't take it in his stride.

Jules Kounde has a crack from range but can't keep his effort down. Why not, eh?

Raphinha was not included on the shortlist for the Ballon d'Or which was announced yesterday.

He's going some way to making that look like a major oversight with his performances so far this season.

A couple of times Viking have been caught out by Stuttgart's long balls over the top.

Absolutely torrential rain in Barcelona and the first few rows of the Camp Nou have a lot of empty seats.

I reckon a lot of fans are still hiding in the concourses.

Off we go in Barcelona and in Stuttgart.

A moment of silence is observed before both matches to pay tribute to the victims of the devastating flash floods that struck Nepal.

The players are out in Barcelona and in Stuttgart.

Night two of the Champions League is almost under way.

Meanwhile, in Barcelona it is absolutely chucking it down.

But the Nou Camp looks fantastic all lit up and ready for some European action.

Viking face Bayern, Atletico, Napoli and Aston Villa, but Norwegian football is full of clever, competitive coaches, players and teams. They could make it to the knock-outs.

A lovely sunny evening in Stuttgart, not something the Viking players will be that used to.

Based in the Norwegian city of Stavanger, the Champions League debutants are used to summer highs of 18C.

Their fans have all got their t-shirts on and are soaking up the atmosphere.

Arsenal

Arsenal boss Mikel Arteta: "I’m really excited.

"We know what this competition means to all of us, the experience of last year as well, so we need to start with the first game in a really, really tough place, but really excited to start the campaign.

"Start well tomorrow; that's the only thing we can do. Start by putting in a big performance tomorrow to increase the probability of winning the game."

Arsenal might be the overall favourites for the tournament but it's a tough old start they've got away to Serie A side Napoli.

Will they impress with a statement performance later on?

I thought Arsenal were fluid last season, but I feel like they are actually more fluid this season.

Arsenal look the most ready I've seen them in a long time at this stage of a season.

Usually, at this stage, teams are still getting up to speed and there are a few flaws here and there, but they look top.

It comes down to what Mikel Arteta has done over the summer, for me. I don't mean in terms of recruitment, but more so what he has done on the grass. It is all about his ability to make his players better.

Arsenal look so far ahead of everybody else at the minute it is unbelievable.
