Both teams are in magnificent form and they're running away with their leagues.

PSG have peaked at the right time and you wonder whether it's going to be a game where both teams struggle to break each other down.

It's certainly a fascinating one.

Back under way in this evening's 17:45 kick-off and it's Inter Milan who have just doubled their lead through a fantastic Lautaro Martinez finish.

Simone Inzaghi's side are now well in control of this tie.

Paris St-Germain were heading out of the Champions League after just four points from their first five games in the group phase.

Then Luis Enrique's side beat RB Salzburg (3-0), Manchester City (4-2) and Stuttgart (4-1) to make it through to the play-offs.

They then beat French rivals Brest 10-0 on aggregate to set up a first meeting with Liverpool for seven years.

PSG are bang in form going into this having won their last five games in the Champions League.

Cody Gakpo is not involved for Liverpool at all tonight after picking up a knock in training. Andy Robertson returns to the starting XI in place of Kostas Tsimikas.

Under Xabi Alonso, Bayer Leverkusen are unbeaten in their six matches against Bayern Munich across all competitions (W3 D3).

Leverkusen have kept a clean sheet in three of their last four against them, after not keeping any in their previous 15 games against Bayern beforehand (42 goals conceded in those 15 matches)

Let's head over to Germany where a monstrous tie is about to take place.

Bayern Munich's Harry Kane is so often the difference maker for his side and he'll be wanting to have a huge impact tonight.

Paris St-Germain boss Luis Enrique: "The first match, I don't think it will define who will qualify but it's true that it's a very, very important match for us.

"It's difficult for our opponents to play at the Parc with the pressure and the atmosphere. It's extraordinary. We are a collective, sometimes it is the substitutes who are the most important. Everyone will have their role.

"We're going to try to keep the ball and not suffer too much on the transitions. If we manage to impose our style of play, we'll manage not to suffer too much."

The calm before the storm...

Paris St-Germain are a genuine threat. They are a serious team. There is absolutely no reason why they cannot win this competition. If Liverpool get through they can say ‘we’ve beaten one of our rivals to win this competition’. But equally there is every reason to be believe that if PSG beat Liverpool they may feel there is nothing left for them to fear in Europe.

At least Liverpool don't have to worry about Neymar this time.

The last time the clubs met in November 2018, the Brazilian hit the winner for PSG, a 2-1 Champions League group win in the French capital.

While Neymar has since left and now plays in Brazil for Santos, Liverpool's team that night included Alisson, Virgil van Dijk, Mohamed Salah and Joe Gomez, while Trent Alexander-Arnold was an unused substitute.

Despite defeat to PSG, the Reds went on to be crowned champions of Europe that season after beating Tottenham in the final.

PSG still have talent, but it feels that the superstars they had before, maybe they weren’t a team.

They’ve gone down a different route and this is a dangerous game for Liverpool, but they would have preferred to play Benfica.

PSG have players who can hurt Liverpool. Liverpool have their work cut-out to beat PSG.
