Strong start from Liverpool, high tempo stuff although that corner comes to nothing. Fabinho snaps into a tackle.

Lionel Messi and Andy Robertson are having words and the referee has to come over to sort it out. Robertson pushed Messi in the head after that early challenge. He's up for this.

The crowd have done their bit as we knew they would and now it's over to the players. They don't need to do anything crazy, just be patient.

A headless chicken of a start! Lionel Messi goes on a mazy run, he's stopped and then Sadio Mane crosses from the left, Jordan Henderson is close to meeting it and it's turned away for a corner...

Away we go!

Here we go then. Can Liverpool's makeshift attack pull off something verging on the miraculous?

Excellent atmosphere inside Anfield, as you'd expect. Barca are lined up in a fluorescent yellow number. Here come the sides!

Barcelona's last three defeats in Europe have all been by a scoreline that would take Liverpool through, or to extra time at least.

They lost 3-0 at Roma in the 2017-18 quarter-finals, 3-0 at Juventus in the 2016-17 quarter-finals and 4-0 at Paris St-Germain in the 2016-17 last 16.

On the cards?

Aaron: The only positive for me is the fact that Liverpool are the one team I'd back to upset the odds in Europe. They've made a habit of it over the years. Let's give a good account of ourselves and then what'll be will be.

zangaswagga: I would definitely have started Sturridge. Big game player.

J Staggs, High Wycombe: Liverpool need to be attacking those wide channels against this Barca side who play very narrow. Gonna be a cracker.

The Liverpool players are roared down the tunnel after their pre-match warm-up but those cheers quickly turn to jeers for the Barca team, who have a quick huddle before they disappear.

It's fair to say the atmosphere has turned up a notch or two in the last few minutes, and so has the volume.

Liverpool

Liverpool boss Jurgen Klopp, speaking to BT Sport on being without Mo Salah and Roberto Firmino: "With Mo and Bobby it would have been a massive challenge as well, that is how it is in football.

"I am happy for the boys that get the opportunity tonight and they all have to deliver. It is a big one and we will try really hard."

On how his front three will line up: "The positions I give to the players is for when Barcelona have the ball and we need to be organised, all the other moments the players have to be free."

YNWA time at Anfield...

This is the oldest starting line-up Barcelona have ever fielded in the Champions League - an average of 29 years, 216 days. Their previous record was set in the first leg.

In the first leg it was one of the most complete performances from Lionel Messi. He was talking to the players before the game.

He was trying to disrupt the pace of Liverpool and was almost trying to do it by himself as he felt he needed to do it.

The Champions League has been a bit of an obsession for Barcelona. In one of the papers today the headline was "Now or never".

Jurgen Klopp sums up his team selection tonight: "Well, we start with 11, so that's good."

Luis Suarez did a magnificent job for Liverpool when he was here. But now he's being paid by Barcelona to score his goals for them so do your celebration if you want.

When I went back to Blackburn with Newcastle you get bits off the crowd, that's part of it, and I never thought 'if I score I'm not going to celebrate'.

I've not got an issue with Suarez scoring and celebrating.

The BT cameras are focused squarely on Luis Suarez, back on his old hunting ground. He was a brilliant player for Liverpool. Can he help knock them out tonight?

The Liverpool players are out for their warm-up, greeted by a massive roar from the home fans. Anfield is a sell-out tonight, and it is fast filling up.

You hear a lot about the magic that happens under the lights here on European nights, and although the Reds need something very special to happen, at least they have the statistics on their side, as well as their famous support.

Liverpool are unbeaten in their last 21 European home games (W15 D6) and have never lost at Anfield at this stage of the European Cup or Champions League either, winning eight of their 10 matches, and conceding four goals.

Two of those came in last year’s semi-final, when Liverpool beat Roma 5-2. The scary thing about their task tonight is that even a repeat of that scoreline will not be enough to see them through.

The Liverpool player was "ruled out as a precaution due to a slight muscle strain".

I think Mauricio Pochettino got his tactics wrong in the first 25 minutes of the first leg and then Tottenham started to grow into the game. Spurs' away form isn't very good, they've lost nine of their last 10, but they have to go all in and they know what they need to do.

Dele Alli needs to step up and he has not had a good season but Tottenham have the players to hurt Ajax.
