Think we're all in agreement when we say Julian Alvarez is one of the best players in the world.

The former Man City forward curled in a beautiful free-kick to put Atletico Madrid in the lead in the first leg, but could he be doing that for Barca next season?

It's not surprising Barca are looking to replace an ageing Robert Lewandowski and an inconsistent Ferran Torres with Alvarez.

He has a 500m euros (£435m) release clause, and Atletico will not sell for less than 100m euros (£87m), a fee Barca's current finances cannot support.

Alvarez said: "I'm happy here," but left the door slightly open to the Catalans, when he also said about his future: "I don't know. You never know."

It's going to be fascinating how this plays out.

PSG have a two-goal lead and if Liverpool start to open up and leave gaps at the back, that will suit PSG down to the ground.

Liverpool are going to have to play this game very cautiously at times which doesn't sound great for the fans going to the game.

But you have to try and play it in stages and maybe get a goal just before half-time.

Lamine Yamal's a special talent, special player. He's already a superstar, he's the next icon of the game. You can see him standing shoulder to shoulder with the greats. He's a sensational footballer.

Tonight is just the second time Liverpool's big three summer signings (Wirtz, Isak, Ekitike) have all started a match together in all competitions, after their 5-1 win at Eintracht Frankfurt in October.

This is the start of a huge week for Atletico Madrid.

Tonight they can book their spot in the last four of the Champions League and then on Saturday, they take on Real Sociedad in the Copa del Rey final.

A huge, huge few days for Diego Simeone and his men.

There are 3,000 PSG fans at Anfield.

And some of them look like they are celebrating before a ball has been kicked in anger in this second leg.

Flowforth: For Liverpool to have a chance they have to be bold - and I fear that Slot will be too cautious. We need the unpredictability of Rio and Mo on the wings - and rotate Ekitike and Isak in the middle. Play Wirtz in a free role to pull the strings - and Dom and Grav/Macca behind. No more odd formations - play Frimpong and Robbo with our best two CBs. Be patient and don't concede - get the first goal.

Well, the fans are doing their bit.

Fifteen minutes to kick-off and Anfield is bouncing.

The Kop is belting out song after song.

I watched Alexander Isak come on at the weekend, and he looked so disinterested and so unfit. That is a big gamble for him to be starting. Fingers crossed he is ready for the challenge.

On Arne Slot, who revealed that Alexander Isak won't be able to play 'much more than 45 minutes' in his pre-match interview...

If Isak is on fire, he might feel like he has more in him. If someone is only playing 45 minutes, you'd imagine Arne Slot has already told someone, maybe Mohamed Salah, that he is coming on at half-time. If that doesn't happen, there is another issue, another situation.

A big, big night for Alexander Isak.

He has an opportunity to pay back a slice of that £125m British record fee.

If there is one team that can believe they can do it, it's Barcelona. The team is super offensive. There is a lot of energy, there is a lot of legs, but at the end of the day it is all pretty much down to Lamine Yamal. If he can deliver, then they can qualify.

Regarding Liverpool, I'll be honest, I don't think Arne Slot will be here at the start of next season. I could certainly see Andoni Iraola here at Anfield.

This is a big week for Arne Slot.

They play Everton at the Hill Dickinson on Sunday which is another huge game. They have also got Manchester United (away) in their remaining fixtures as well.

If he is to lose a few games on the bounce, and this one heavily tonight...I think the Anfield crowd are starting to get a little bit frustrated with him.

You do not want to lose the crowd.

For me, Luis Enrique's dream is to come coach here in Liverpool, Manchester or London at one of the big English clubs. He is made for this league, he is made for this culture.

He is a great coach, but I think he will work so well with the right English club. It is inevitable that we will see him in the Premier League on the bench.

Luis Enrique knows exactly what kind of atmosphere his PSG players are in for tonight - after experiencing The Kop for himself.

After retiring from playing, the two-time Champions League winning boss came to watch Liverpool and stood on The Kop with home fans to sample the atmosphere.

"I don't remember the match but it was nice," said Enrique at his pre-match news conference on Tuesday.

"I wanted to live as a supporter at one of the best stadiums in the world. I remember I got the tickets because Luis Garcia was playing here."

Later on Tuesday, Garcia - who won the Champions League with Liverpool in 2005 - wrote on social media: "It was Everton Luis! Special match. Great old memories."

Barcelona are reportedly concerned about the quality of the pitch at the Estadio Metropolitano.

And it's not the first time the pitch has been criticised. Both opposition and Atletico players in the last few months have had their say on its condition.

Barcelona head coach Hansi Flick has reportedly discussed the pitch with the Uefa match delegate.

There have been several high-profile incidents of players slipping on the surface in recent months, notably in Barca’s 4-0 Copa del Rey defeat in February and Tottenham's Champions League loss.

It's one to keep an eye on.

Bored: You’ve got to go in with hope otherwise you are already defeated. History tells us anything can happen but Arne Slot needs to create the mood and platform for that and that is the biggest question.

Robbie Fowler

On Arne Slot, who revealed that Alexander Isak won't be able to play 'much more than 45 minutes' in his pre-match interview...

I can't believe he's done that. He has come out and more or less given the tactic away, straight away. If he changes after 45 minutes, there is going to be a change in the tactics, formation or dynamics of Liverpool. It doesn't make sense for me.
