Jürgen Klopp's reaction

The boss was satisfied by a job well done post-match - but he also warned that Liverpool will have to overcome a fightback from Porto next week if they're to advance to the semi-finals.

Read a summary of Klopp's press conference here.

Jordan Henderson speaking to BT Sport after the game...

"I think we've got to be pleased with the 2-0. There were some good moments in the game [but] obviously we can do better. 2-0, clean sheet - that's important.

"Obviously we wanted to come out in the second half and score one or two more if we could, but that wasn't the case."

Jürgen Klopp in his post-match press conference...

"It was a good game. In a lot of moments we deserved the win 100 per cent, we scored two wonderful goals. Overall a really good performance. They had a few too many set-pieces, but we defended them well."

Lovely link-up between Milner and Origi down the left earns a corner, which is cleared for another corner that comes to nothing.

Liverpool closing in on a fine first-leg result here.

Chance for Porto.

Militao intercepts Henderson's pass to Salah and sprays a great ball over the top to Marega, but his left-footed shot goes over the bar.

Porto have come back into it here, and Marega works Alisson with a low drive from an angle before Mane curls wide at the other end.

Liverpool have been superb in this last five minutes or so, and Alexander-Arnold is a fraction away from getting his shot off after playing an intricate one-two with Salah inside the area.

After a spell of Porto pressure, the Reds turn defence into attack in an instant and Salah gets a shot off after being found by Alexander-Arnold, but it's partially blocked and Casillas gathers.

Take a look at the story of that first half in stats below...

A rapid breakaway, started by Alisson's throw, ends with Keita just over-hitting an attempted throughball to Mane, allowing Casillas to gather.

Firmino volleys over!

Another good move from the hosts ends with Henderson crossing to our No.9, but his shot narrowly clears the bar.

Great save, Alisson!

Nearly an immediate response from Porto, but the Brazilian denies Marega.

There's then a VAR check for a potential penalty for handball by Alexander-Arnold, but no spot-kick is awarded.

Wonderful, wonderful football from the Reds!

Henderson picks out a beauty of a slide-rule pass into Alexander-Arnold's path, and the right-back picks out Firmino free inside the six-yard box to roll it home.

SIM, SENHOR!

Salah so close to a second!

Mo reads an under-hit back-pass, rides a tackle and is one-on-one with Casillas.

He tries to place the ball beyond the 'keeper and does so, but his shot rolls just wide.

Salah, who looks very much in the mood tonight, earns the applause of Klopp, his teammates and the home support for a brilliant piece of tracking back that thwarted a potential Porto counter.

Van Dijk then gets a crucial foot in to block Marega's shot from close range, before Salah tests Casillas from range with a well-struck volley at the other end.

Liverpool, lifted by Keita's goal, have been in complete control here, save for the frst couple of minutes or so.

The Reds are pushing and probing, but Porto are standing firm at the moment.

Get in, Naby!

Keita's second goal in as many games opens the scoring. Mane gets in down the left and finds Firmino, who tees up our No.8.

His shot takes a big deflection off Torres, which sees Casillas wrong-footed as the ball loops into the top corner.

What a start!

Marega has the first attempt of the game after a bright start by Porto.

The visitors' No.11's half-volley is miscued wide from around 12 yards out.

And we're off!

Porto, attacking the Kop end, get us under way.

Spine-tingling

'You'll Never Walk Alone' always sounds that little bit extra special on European nights at Anfield, doesn't it?

Kick-off is just a few minutes away now...

Reds arrive at Anfield

Klopp explains team selection

Jürgen Klopp has explained how Dejan Lovren is ready to return to Liverpool's starting line-up as the centre-half makes his first appearance since January.

Joe Gomez is also part of a Liverpool matchday squad for the first time in 2019 after recovering from a lower leg fracture.

“Dejan has been training for about three or four weeks already," the Reds boss said. "Joel [Matip] played so many games, so it’s just to use fresh legs and the energy of Dejan. That’s pretty much all we changed.

“Joe actually should have played a couple of minutes today in an internal friendly game behind closed doors, but Alberto [Moreno] was not ready for the bench and we don’t have a lot of left-back options left, so that’s why Joe is in.”

Behind closed doors

In formation

It's 4-3-3 for the Reds and 4-4-2 for the visitors tonight, Opta reckon...

They're back!

How good is it to see these two back involved tonight?

In opposition

Porto team: Casillas, Maxi, Felipe, Militao, Alex Telles, Corona, Danilo, Oliver, Otavio, Marega, Soares.

Subs: Vana, Hernani, Brahimi, Andre Pereira, Fernando Andrade, Diogo Leite, Bruno Costa.

TEAM NEWS

There are three changes for Liverpool against Porto tonight as Jordan Henderson, Dejan Lovren and James Milner return to the starting XI at Anfield.

Joel Matip and Georginio Wijnaldum drop to the bench, while Andy Robertson is suspended. Joe Gomez is on the bench.

Liverpool: Alisson, Alexander-Arnold, Lovren, Van Dijk, Milner, Fabinho, Henderson, Keita, Salah, Mane, Firmino.

Substitutes: Mignolet, Wijnaldum, Gomez, Sturridge, Shaqiri, Origi, Matip.

Matip speaks

A Joel Matip interview features in this evening's matchday programme.

The centre-half is currently loving life as a permanent fixture in Jürgen Klopp's line-up, having started the last 13 matches in all competitions.

It's a particularly pleasing run for the defender after he suffered a broken collarbone in December.   

"Of course injuries belong to the life of a football player and you are always happy if you are fit and you are able to play," he says. "I hope it stays like this.

"I had to wait for my chance earlier in the season and, of course, it is a shame that Joe [Gomez] and Dejan [Lovren] were injured but, as I say, I have had my own problems with injuries and this is part of the game."

Mo records...

Mohamed Salah comes into tonight's game having become the fastest player to reach 50 Premier League goals for Liverpool in the club's history.

Reds v Casillas

The Porto goalkeeper is in line to face Liverpool for the sixth time in his career tonight. Casillas has experienced two wins, two defeats and one draw - in the last-16 second leg of 2018 - against the Reds so far.

After the reception he was given by the Kop last year, he commented: "I would like to thank the Liverpool fans for that lovely detail. Applauding a player from the opposite team does not happen very often."

Van Dijk's warning

Everyone inside the Liverpool camp has been at pains to stress that last season's 5-0 aggregate win over Porto will bear little - if any - relevance to their rematch over the next eight days.

And Van Dijk was no different when he sat down for a pre-match interview with us at Anfield yesterday.

"They obviously don't want the same as what happened last year," insisted the No.4.

"They're in the quarter-finals of the Champions League and that's not for no reason. They deserve to be where they are right now so it's going to be unbelievably tough to beat them."

'My football dream'

We've just caught up with some more Porto supporters in the city centre and it's fair to say they're relishing the opportunity to visit Liverpool for this tie.

"It was my football dream to come to Anfield and see Porto v Liverpool," they told us.

"I think we can win but it's very, very tough. We are missing some key players. It will be very tough but we will see."

Pep's Porto reunion

"Porto made an impact on me as a coach, but even more as a person."

Liverpool assistant manager Pepijn Lijnders learned a large part of his trade as a coach for tonight's opponents during a seven-year stay in Portugal.

And he opened up to Liverpoolfc.com about his time with Porto and the lessons he brought to Merseyside from the Portuguese club in this fascinating interview.

Last time out

How the last eight looks

It's a busy midweek across the Champions League, of course, with three other ties scheduled for Tuesday and Wednesday. The winners of the meeting between Liverpool and Porto will progress to take on either FC Barcelona or Manchester United.

Stat attack

Klopp's message to the supporters

Liverpool's last-minute winner against Tottenham Hotspur at Anfield not only earned three valuable points - it taught the manager a new phrase.

And Klopp has asked for a similar atmosphere for this evening's first leg, in his absorbing matchday programme notes.

"I've mentioned before that the supporters were a key factor in our win against Spurs and there is no doubt we need them all at their best for this game," he writes.

"Our fans are knowledgeable and will know Porto have experience and quality in abundance and that Anfield needs to be on its toes for the entire 90 minutes to give us that added energy that can be our X-factor.

"I heard, after the Spurs game, the phrase that the Kop 'sucked the ball over the line'... There isn't really a German translation for this but I know the sentiment is based on willing the goal. I love this – really love this.

"It is true that the supporters can make the difference and even though I would love it to have been credited to Mo I am comfortable with it being chalked down as one for the Kop against Tottenham.

"The same passion tonight is what we need and I'm sure what we will get."
