While it's half-time, here's a bit more on what is happening in Serie A, where Napoli have not turned up for their match at Juventus.

Juventus President Andrea Agnelli and the club's Head of Medical Department, Luca Stefanini, have held a press conference.

"Today, we were to come here to watch one of the best matches of the season," Agnelli said.

"Instead we find ourselves managing a complex situation, but the issue is rather simple."

He added: "As for the sporting rules, they are clear: those who do not show up face disciplinary sanctions. The Sporting Judge will be able to speak tomorrow."

Absolutely no added time whatsoever and the whistle goes for half-time as soon as the clock hits 45 minutes.

It's all even at the break, which is probably fair based on what we've seen so far.

Just wide!Lionel Messi cuts in from the right, switches the ball onto his left and curls a shot just beyond the far post where Antoine Griezmann was also lurking.

Philippe Coutinho presses high and regains possession for his side.

Lionel Messi picks it up and runs at the Sevilla defence, as sight which has historically not ended well for the visitors, but three players are onto him quickly and eventually the ball is cleared.

Barcelona are creeping up towards having 50% of possession for the first time in this match.

Lionel Messi drops deep to take charge for the hosts and skips away from one challenge before he's brought down recklessly by Joan Jordan in the middle of the pitch.

There's no immediate rush to get the ball into the box though, as Ronald Koeman's side begin to assert themselves.

There's a great intensity to this game.

Suso fires into the side netting after breaking clear for Sevilla and moments later Ansu Fati is racing away down the left for the hosts.

Fati is quickly crowded out by Sevilla defenders before he can pick out a or a shot at goal.

Breathless.

Lionel Messi tries one of his increasingly frequent shots directly from a corner.

Will he ever score one of those?

He wraps his foot nicely around this one but Bono leaps off his line to catch it.

Ansu Fati fires straight at Bono after being found on the edge of the penalty area by Lionel Messi.

Fati had time to pick his spot but his shot was rushed and the chance disappears.

Barcelona attempt to play out from the back but Sevilla are all over them and, once again, they win back possession almost immediately.

The visitors then work the ball patiently up the pitch and former Barca player Ivan Rakitic wriggles his way into the area, but there's nobody in to meet his hopeful cut-back.

Antoine Griezmann finds the side-netting. He really should have found the target there.

Ansu Fati sets the forward free but, under pressure, Griezmann stabs at the ball and Bono is rather relieved to see it roll harmlessly wide of his near post.

Sevilla combine brilliantly and at real pace in attack as Lucas Ocampos drives his side forward.

The winger delivers an inviting cross into the penalty area but none of his team-mates can add the finishing touch - which really is all it needed.

Jordi Alba takes aim from 30 to 40 yards out from goal and forces Sevilla keeper Bono to concede a corner.

Better safe than sorry with those...

Fortunately for him, Barca can't make anything of the set-piece.

Sergio Roberto wins a free-kick in his own half to allow both sides a bit of a breather but Barcelona can't keep hold of possession.

They've had little over a third of the ball after 15 minutes at the Nou Camp.

One minute and 45 seconds between those two goals, to be exact.

It's all rather frantic at the moment as both sides try to wrestle control of the game.

It's been a bright start by Sevilla.

Lucas Ocampos lines up a shot from the edge of the area but that is well blocked.

Pablo Sanz is the man on the touchline for Sevilla tonight with Julen Lopetegui in the stands due to a suspension.

The visitors get the first chance of the game but Lucas Ocampos heads narrowly over from close range for the visitors.

Just how much do Barcelona love facing Sevilla?

• Sevilla are winless in their last 17 La Liga games against Barcelona at the Nou Camp.
• Barca have not lost in 25 of their last 26 league games against Sevilla.
• The hosts are the team with the most wins (83) against Sevilla in La Liga history.

And, of course...

Lionel Messi has scored more goals against Sevilla in La Liga than against any other opponent, with 29, and 37 in all competitions.
