Harry Kane smashes a shot on goal from a tight angle and wins a corner that again Spurs cannot profit from.

As is stands, Spurs are going through too - but only thanks to PSV's scoreline at Inter Milan.

Here's what that Mo Salah strike means* in the grand scheme of things...

*As it stands - the most crucial three-word phrase in football

Kalidou Koulibaly with a 'robust' challenge on Mohamed Salah. He clattered him. Into the book he goes.

Ieuan: When we need him the most Mo Salah comes up with the magic

steveygeesings: Salah is a one season wonder though.

Ed: Salah. Brilliant. Despite ref wearing Napoli colours

Five to go until the break.

Can Spurs join Liverpool in finding the net?

Since Liverpool have scored, Napoli have had two or three dangerous attacks. Liverpool have come off the pace and they are asking for trouble.

Liverpool sent a little warning as space opens up for Napoli down the left wing. It's so hard to keep a hold on players like Lorenzo Insigne and Dries Mertens.

The Italians will want to end this half the stronger and build from there. There are a few tears in the away end already.

Liverpool had been pushing Napoli further and further back and there was a sense the goal was coming. Fair for say Napoli keeper David Ospina did not cover himself in glory with the manner in which he was beaten at his near post - but not many people in here care.

Barcelona have found the back of the net in 28 of their last 29 Champions League home games.

Son Heung-min with another poor effort. There is no power on this dribbling low effort from the edge of the box. Another great driving run from Moussa Sissoko - the man transformed - to set him up.

What a time to score. Ten minutes before the break.

As is stands - Liverpool are going through in second place behind PSG.

"Ooooooh!" is probably the noise which Thomas Tuchel is making in his head. The PSG manager puffs out his cheeks as he watches his side twice go close to doubling their lead.

First Neymar cuts in from the left and unleashes a fierce shot which the Red Star keeper saves, before Angel di Maria flashes a shot just wide seconds later.

Where is the goalkeeper? He tries to read the cross and goes early but he leaves a gap between his legs. Liverpool lead.

Mohamed Salah set free down the right and he closes in on goal. He looks for the cut-back with his team-mates loading up, but Raul Albiol stands big to fence away his little chip.

Still we wait for a big chance.

What a chance. A huge moment.

Son Heung-min is through on goal, with time to think on the finish.

Jasper Cillessen just stands big - and when the moment comes he stretches down to block with his legs. Son had to find the net there.

This match has certainly lived up to the pre-match hype, although there is just one thing missing.

A shot on target.

None of Liverpool's four efforts - from James Milner (7), Roberto Firmino (9) and Jordan Henderson (14) - have tested David Ospina, while Marek Hamsik (17) fired narrowly over the home bar.

This is a good spell for Spurs. They win another dangerous free-kick on the edge of the Barca box. Thomas Vermaelen with an untidy lunge on Christian Eriksen - possibly deserving of a yellow. He didn't look in control.

Harry Kane has picked the ball up. He strikes it straight into the two-man wall.
