The visitors seeing most of the ball, but they are playing it patient. Inter players are hunting at speed and in packs to try and win the ball back.

Ooof. Rodri blasts the ball straight into Tyler Adams' face and the Leipzig man needs treatment. A bit of blood and he looks shaken.

What a fantastic chance.

You get Andy Robertson in that sort of position and you know the ball's going to get put in the right place.

Had Divock Origi missed that, Jordan Henderson was waiting at the back post for a tap in, so well done him for getting into that position.

Liverpool are ripping through Milan at every opportunity.

It comes down the left again, with Andy Robertson finding Diogo Jota, who turns on to his left foot and fires a shot that is blocked.

The first goal of the 20:00 BST games has come with a Sebastien Haller header putting Ajax 1-0 ahead at Sporting Lisbon in the 68th second.

Oh, good chance!

Liverpool tear forward again with Andy Robertson found by Diogo Jota on the overlap. The Scottish full-back's cross is hit first time by Divock Origi, but sliced across goal and wide.

Lionel Messi's first ever Champions League touch for a team other than Barcelona but his pass is beyond Kylian Mbappe.

That's a 0% passing accuracy...

Leipzig have an attack in the first 20 seconds or so but Nathan Ake stops the ball reaching Christopher Nkunku in the box.

Liverpool on the front foot. Naby Keita has a pop from range but it is blocked, before Divock Origi has the ball nicked off his toe in the box.

The crowd are up for it, for sure.

Right then, away we go. Six Champions League matches, two of them featuring English sides, one of them featuring a certain Lionel Messi, all of them under way.

If you watch Lionel Messi and don't watch the rest of the field, for the past three or four years, he doesn't move.

He never, ever chases back, he just walks into space and then explodes for short periods of time, hence his career will go on for a good few years yet.

I can see that in Mo Salah already. He's learned that he cannot put all his efforts in to chasing full-backs back and he needs to allow that to happen - and his manager gets that too.

In short, I wouldn't be surprised if he does go on into his mid-thirties.

Manchester City

Pep Guardiola has just told BT Sport that John Stones - who is yet to play this season and is named on the bench for this game - has been "injured from the national team".

He adds: "It's the same with Aymeric Laporte."

Guardiola says he hopes it is the first of "many starts" for Jack Grealish in the Champions League.

On what sort of game he is expecting, he adds: "So intense. Leipzig are so aggressive. It's important we start correctly. You must win your home games in the group stage. We know it."

Simon Gleave, head of sports analysis, Nielsen Gracenote: "Manchester City are second favourites to win the Champions League behind Bayern Munich according to the Euro Club Index (www.euroclubindex.com). Last season's losing finalists are given 17% chance of lifting this year's trophy. City are in the only group in this year's competition which contains three of the best 16 teams in Europe as RB Leipzig were the strongest of the third seeds, ranked 15th in Europe by the Euro Club Index. This has had a small effect on City's chance of progress to the knockout phase, reducing it from 91% to 89%."

Simon Gleave, head of sports analysis, Nielsen Gracenote: "Liverpool were hit particularly hard by the Champions League draw. Atletico Madrid are one of the four best top seeds, FC Porto are the second best third seed and AC Milan are the strongest of the bottom seeds. Liverpool are still favourites to progress to the next round but their chance of doing so has declined from 86% to 75% after ending up in this year's 'Group of Death'. Liverpool's chance of winning the Champions League is 7% according to the Euro Club Index."

Sandro Tonali has been called 'the new Pirlo' ever since the start of his fledgling career - with the nickname first mentioned before he had even played a minute of senior football.

So when AC Milan's 21-year-old midfielder lines up at Anfield on Wednesday for his Champions League debut, he won't be put off by such lofty expectations, even if his game is actually styled on a very different Milan legend.

Tonali scored his first goal for AC Milan with a brilliant free-kick against Cagliari two weeks ago, an almost identical effort to Andrea Pirlo's debut goal for the club versus Parma back in 2002. The 'new Pirlo' tag was on everyone's lips again.

Read the rest of Michael Yokhin's feature on Tonali on the BBC Sport website.

Olivier Giroud isn't the only underappreciated former Chelsea player currently plying his trade at the San Siro with AC Milan.

At the back, they have £25m summer signing Fikayo Tomori, who appears to have finally found a club to fully back his undoubted talent.

And in midfield, the lesser spotted Tiemoue Bakayoko is in the mix. He may not start tonight, but the former Monaco player is an awful lot closer to the first team than he was during the majority of his time at Stamford Bridge.

If any of them want to discuss what life can be like after a stint at Chelsea, they need only give Mohamed Salah a nudge. He's done alright for himself.

AC Milan come into tonight's game as one of three Italian sides still with a 100% record in Serie A after three games.

Stefano Pioli's side have been mighty impressive so far, with Lazio their latest victims, taken down 2-0 on Sunday.

Olivier Giroud - yep, him - has two goals in two games, with young Portuguese forward Rafael Leao also chipping in with a couple.

Paris St-Germain sporting director Leonardo does not expect Kylian Mbappe to leave at the end of the season and is confident the France forward will sign a new contract.

Mbappe is out of contract in June 2022 and can sign a pre-contract agreement with another club in January.

He was the subject of a £137m bid from Real Madrid during the transfer window.

"I don't think anyone here sees the future without him," Leonardo told Canal Plus.

"I don't see Kylian leaving at the end of this season. Mbappe's relationship with PSG is deep."

World Cup winner Mbappe - who joined from Monaco in 2017 in a deal worth £166m - has won three Ligue 1 titles and three French Cups with PSG, as well as helping the club reach their first Champions League final.

If you'd have said, with the quality of players Pep Guardiola's had, the money, would you have guessed they'd have won the Champions League by now? I'd have said yes, absolutely.

That's why it's still a question, with the investment, the beautiful football, it's still not happened.

I think it's fair enough to ask those questions, because he should have done it by now. I wish he had, because he deserves it.

Whoever comes in next if Pep Guardiola doesn't win the Champions League - it's going to be the same conversation.

They celebrate league titles, but there's that gap in their legacy with the champions League. Until that is met, the question will always remain, whether that's fair or not.

It's one of the toughest competitions to win because it feels like there's not a set formula for finding success in it. Pep sounds so frustrated, like he's literally had enough and he's going: 'Here we go again, it's that time of the year, let's do this.'

For him, it's business as usual, he'll try and get it done.
