Napoli's first big chance. Victor Osimhen is sent away by a lovely ball down the left, runs in between two defenders and is denied by Marc-Andre ter Stegen's legs at his near post.

Napoli's key man up front Victor Osimhen lands awkwardly and needs treatment but he's OK. He's still wearing a mask from a facial injury suffered a couple of months ago.

First sniff now for Pierre-Emerick Aubameyang but the player who promised to play for Real Madrid one day lashes a shot wide from 25 yards.

Another Barcelona chance now as Nico controls the ball on the edge of the box, steps past a defender and then hammers in a shot, saved at the near post.

Sulaimon Adelekan: Xavi took over when Barcelona were 9th and now they are 4th. The progress has been slow and steady, also the January recruit were indication of intent.

Gerard Pique heads behind Piotr Zielinski's cross and Napoli have a corner.

The corner comes to not very much.

We've got one goal so far in tonight's Europa League games. It has come at Zenit St Petersburg, where Guido Rodriguez has given Real Betis the lead.

It remains goalless in the game between Borussia Dortmund and Rangers. You can follow that match here.

This has the feel of a Champions League group game in October.

Excluding qualifiers and the Super Cup, each of Barcelona’s last 191 games in European competition have been in the Champions League.

Barcelona have lost three of their last five home games in Europe, as many as in their previous 74.

Good start for Rapid Vienna against Vitesse in the Conference.

First chance of the game as Pedri is picked out in the box his rising drive flies just over the bar.

Victor Osimhen has his first run at Barcelona's defence but can't do anything with it. Same at the other end for Pierre-Emerick Aubameyang.

I wonder when the last Thursday night European game at the Nou Camp was.

Adama Traore is double teamed by two Napoli defenders after 60 seconds.

Under way at the Nou Camp.

BBC Scotland have a separate live text of Rangers' trip to Borussia Dortmund.

Erling Braut Haaland is out injured.

We'll let you know what's going on in that game.

"It's an opportunity," said Barcelona boss Xavi.

"The main objective for the season is to get into the Champions League for next year and there are two ways - finish in the top four in the league or win the Europa League.

"It is European competition and we need the fans. We are expecting a great tie and we want to go as far as possible."

Barcelona, who lost three of their six Champions League games 3-0, are currently fourth in La Liga.

Excluding Italian Cups, Napoli's only three major trophies came during Diego Maradona's seven seasons at the club - two Serie A titles and a Uefa Cup.

The late Maradona also played for Barcelona.

Napoli are only two points off the top of the Italian league this season.

Boss Luciano Spalletti said: "If we want to win the competition and donate a trophy to the city, we must be ready for everyone. We can't decide who we play against and when.

"We will play our game, we will not use a special tactic just because it's Barcelona. We try to play as we know. We know that in some moments we will have to defend and in others try to exploit the spaces."

Pierre-Emerick Aubameyang makes his first start for Barcelona in a strong team.

Adama Traore gets his first European game for the club since 2013.

Ex-Manchester City pair Eric Garcia and Ferran Torres are also involved.

Also a strong Napoli line-up.

Striker Victor Osimhen has scored four goals in 168 minutes of Europa League action this season, a goal every 42 minutes.
