Mohamud Ali: With a central defence pairing of Matip and Lovren and Moreno at left back, I have a fear Klopp is complacent here and might easily give away this.

Neymar became the 31st Brazilian to play for Paris-Germain since they were set up in 1970.

By comparison, Real Madrid have only had 24 in their 116 years.

So how has a city without a common climate or language, lacking either a long history or sizeable expatriate population, become a favourite staging post for Brazilians coming to Europe?

If anyone was in any danger of any complacency at Anfield tonight then have a read of Jurgen Klopp’s programme notes and you can practically hear him booming these words out in the dressing room.

“This attitude is not allowed inside Anfield this evening for anyone associated with Liverpool Football Club.

If I was in the FC Porto side this evening I would be looking forward to this match more than any other of my professional career. So we must do more than simply mirror the passion and desire they will show. We must surpass it, we must be at a higher level - players, staff and supporters.”

You have been told.

It might not be the worst thing in the world that Neymar is not playing as you might get a better team spirit. It looks like a classic PSG team and it might work in their favour.

Disturbed by fireworks outside the team hotel at 01:30 in the morning, the Real Madrid team coach arrived through red smoke and flares aplenty outside the Parc des Princes.

Cristiano Ronaldo plays alongside Karim Benzema, who makes his 100th appearance in the Champions League.

PSG have Kylian Mbappe back after missing the last two and he forms a front three with Edinson Cavani and Angel di Maria.

Kylian Mbappe and Edinson Cavani both return for Paris St-Germain after missing their last match - a 2-0 Ligue 1 win at Troyes on Saturday.

Boss Unai Emery makes seven changes from his starting line-up to that game, with goalkeeper Alphonse Areola, captain Thiago Silva, midfielder Adrien Rabiot and forward Angel di Maria the four to keep their places.

Paris St-Germain: Areola, Dani Alves, Thiago Silva, Marquinhos, Yuri, Verratti, Thiago Motta, Rabiot, Di Maria, Cavani, Mbappe. Substitutes: Trapp, Kimpembe, Meunier, Lo Celso, Diarra, Draxler, Pastore.

PSG certainly believe they can go through.

You lose Neymar, you lose your best player. But you might have gained more unity for your team and a better collective. When he plays you give him the ball and wait a bit for him to do something special.

When he’s not there you know you have to do a bit more - so your full-backs have to do more, your midfielders need to run into space. Maybe you would tend to let Neymar do his thing when he’s on the pitch.

However it’s still a big task, to not concede against Real Madrid. I would make Real Madrid slight favourites, maybe 65-35.

The noise has been extraordinary. They really do believe. The history for PSG at this ground, they have had amazing results. They need to be better psychologically, but that is the big question.

Since Cristiano Ronaldo scored twice as Real Madrid came from behind to win the first leg, the champions have won four of their five La Liga matches.

This time last week, they suffered a 1-0 defeat at Espanyol - but have beaten Getafe since then.

PSG as you'd expect have won all four games, including two 3-0 victories over rivals Marseille (one in the French Cup).

Three weeks ago, Liverpool thrashed Porto 5-0 with Sadio Mane scoring a hat-trick.

Since then, they have beaten West ham 4-1 and Newcastle 2-0 in the Premier League to boost their chances of qualifying for the Champions League next season.

Porto have been busier, playing four times in their top flight - winning all of them, including Friday's 2-1 win over old rivals Sporting Lisbon. They are now five points clear at the top of the table.

I don’t think we’re going to get much Champions League drama at Anfield tonight but there’s no denying this is a magnificent stage to play it out on.

The Porto fans are in early to take it all in and they are making one heck of a noise already. There’s clearly a lot of pride to play for from their point of view after their team was humbled at the Dragao.

Flashy stuff!

Former Real Madrid and Germany keeper Bodo Illgner has been speaking to the BBC World Service about tonight's game.

Real have won the Champions League in each of the past two seasons - but sit 15 points behind Barcelona in La Liga.

“The only thing left for them this season is our competition, the Real Madrid competition - the Champions League, where the team transforms.

"Twelve titles in the club speaks its own words, two in a row lately. It is this competition that transforms Real Madrid and transforms the players. It’s hard to explain but it is like that.”

I don't want to say Porto have lost hope but they've made eight changes from a big league game last Friday.

Ben Clarkson: Would've been the perfect opportunity for Klopp to give Solanke a start and get him a goal or two, got a feeling Liverpool will run riot (again) tonight.

As expected, PSG winger Angel di Maria lines up against his former club - effectively in Neymar's place.
