Odegaard that is absolutely unbelievable. The touch and the finish is magnificent.

The two sides are in the tunnel with five minutes to kick-off.

So here is one final reminder of the team news as Arsenal fans Mikel Arteta chant rings out around the ground.

Arsenal: Raya, White, Saliba, Kiwior, Gabriel, Rice, Jorginho, Odegaard, Saka, Trossard, Havertz

Porto: Costa, Mario, Pepe, Otavio, Wendell, Varela, Nico, Pepe, Conceicao, Evanilson, Galeno

Tonight’s referee is France’s Clement Turpin, one of Europe’s most recognisable officials.

Amusingly, some Arsenal fans have been joking ahead of the match that he is Leandro Trossard’s brother.

I can see a slight resemblance in fairness.

For the record, Trossard and Turpin are not related.

As highlighted by Mail Sport’s Isaan Khan, the stage is set with around 20 minutes to go until kick-off with the atmosphere building.

A couple of statistics which should ease the nerves of Arsenal fans.

Porto have only won two of their 22 away games in the knockout stages of the Champions League.

The visitors have never won both legs of a knockout tie in the Champions League.

I have been chuckling to myself in the build-up with Martin Keown having twice on TNT Sports made reference to Porto’s dark arts.

The former Arsenal defender famously never engaged in the dark arts… just ask Ruud van Nistelrooy.

Mikel Arteta did not bite, but Arsenal captain Martin Odegaard has signalled a warning to his side ahead of tonight’s match.

Odegaard has warned the Gunners to expect a lot of time wasting from tonight’s visitors.

The classic team sheet shot from Mail Sport’s chief sports writer Oliver Holt at the Emirates this evening.

It gives me the perfect chance to divert attention from the Champions League for just a moment.

Oliver Holt’s latest column takes a look at the title race, as he argues Arsenal have shown no signs of falling away despite Man City and Liverpool taking the focus after their draw on Sunday.

Can Arsenal fans even dream of Premier League and Champions League this season?

Strange old seasons for Barcelona and Napoli this campaign with both sides well off the pace in their respective leagues.

The Champions League does offer a chance for success though this season.

Here is how the two sides line-up this evening.

Barcelona: Ter Stegen; Kounde, Cubarsi, Araujo, Cancelo; Lopez, Christensen, Gundogan; Yamal, Lewandowski, Raphinha.

Napoli: Meret; Di Lorenzo, Rrahmani, Juan Jesus, Rui; Anguissa, Lobotka, Traore; Politano, Osimhen, Kvaratskhelia.

A very Mikel Arteta line as the Arsenal boss talks about the need for the connection with ‘our people’ to help the team.

Arteta has stressed the importance of the Arsenal fans in helping the club strive for trophies.

It is worth mentioning that the Gunners have won all three of their Champions League home games this season by an aggregate score of 12-0.

I think if we want to challenge as a club again and the club we want to be then we have to leave the magic nights with our people and make it happen,’ Arteta told TNT Sports.

We have been on that ground and know how atmosphere and energy can change mindset, purpose and courage to play.

They have been fundamental in way we want to play.

Mikel Arteta has just been giving his pre-match thoughts to TNT Sports.

The Arsenal boss says his side need to have learned from the first leg defeat last month, after admitting his side did not have enough purpose in posession.

You always do from every game, we are going to try different things to attack better and be more of a threat and put them on the ropes every time we can,’ Arteta said.

They are very intelligent in way they manage the game.

We did in many areas, defensively very strong and had a lot of ball but not with enough purpose or courage and that has to be different.

And here is how the visitors line-up this evening.

It is still so impressive to see Pepe at the heart of the defence at the age of 41.

Martin Keown on TNT Sports has just been urging Mikel Arteta to get bodies around the veteran.

Arsenal’s first leg nemesis Galeno aslo starts, along with Franciso Conceicao, the manager’s son.

That all important Arsenal team news is in.

As expected, David Raya is recalled in goal to replace Aaron Ramsdale after being ineligible to face Brentford on Saturday.

As Sami Mokbel reported, Gabriel Jesus remains on the bench, while there is no Gabriel Martinelli.

Elsewhere in Europe, Barcelona are hosting Napoli at their temporary Olympic Stadium home.

The teams are level following a 1-1 draw in Naples in the first leg of their last-16 tie.

We will be keeping you across all the updates from that one.

As highlighted by the Gunners, team news should be on the way shortly for this 8pm kick-off.

Mikel Arteta’s hands might be tied somewhat with their forward options with Gabriel Martinelli expected to miss out tonight.

Early team news in from Mail Sport’s chief football reporter Sami Mokbel at the Emirates.

It is understood that Gabriel Jesus will not start for Arsenal this evening amid concerns over his ongoing knee issue.

Jesus has not started a match since January 30 due to a knee problem, but has come off the bench in their last two Premier League matches.

Arsenal came unstuck in Porto last month in the fourth minute of stoppage time, after looking poised to secure solid goalless draw in the away leg.

The Gunners had escaped early in the match when Galeno crashed an effort onto the post before firing the rebound wide with the goal gaping.

Galeno made amends with a dramatic winner to ensure the two-time European champions have something to defend heading into the second leg.

Porto showed their ability to soak up pressure and hit on the break in the first leg and you can be sure Sergio Conceicao’s will be looking to do so again tonight.

It is crunch time for Arsenal in the Champions League with the Gunners bidding to reach the quarter-finals for the first time in the competition since the 2009-10 season.

Mikel Arteta’s side must overturn a 1-0 deficit from the first leg against Porto after being stunned late on in the first leg.

The defeat was one of only two the Gunners have suffered this year, with the other coming in the FA Cup to Liverpool.

Arsenal will hope their imperious Premier League form continues tonight to continue their journey in the Champions League.

Stay with us throughout the evening for all the build-up and coverage from the Emirates, as well as updates from Barcelona’s last-16 tie with Napoli.
