Napoli v Liverpool -as it happened
FT: Napoli 2-0 Liverpool!!! Full time in Naples as two late goals from Mertens and Llorente see Napoli claim the three points. Both keepers made a great save and it looked to be heading for a 0-0 draw, but Mertens scored a pen after Callejon dived to win it and then Llorente took advantage of a Van Dijk error to kill off the game. Thanks for joining us and see you again soon!

Liverpool win a corner now.
Liverpool are unlucky to fall behind as a draw would be a fair result.
Adrian makes a great effort and very nearly saves it, but how have Bastian Dankert and Marco Fritz as VARs confirmed that? Dankert is the main man and Fritz has got plenty of previous. Let's put it that way.
The VAR checks it and confirms the penalty!!! Astonishing. And Mertens makes no mistake from the spot!!! Adrian dives to his right and gets his hand to it, but it goes in.
Penalty to Napoli!!!!! Mertens passes to Callejon inside and then Robertson goes in and brings him down! For me, Callejon dives quite clearly. Contact is between none and minimal.
Mane is a whisker away from reaching Alexander-Arnold cross at the back stick.
Llorente has a foul given against him for the pull back.
Napoli sub: Elmas replaces Allan who was struggling a few minutes back.
Mane is denied by Meret just now in a rare Liverpool chance.

Still no goals here and Liverpool have weathered Napoli's 10-15 minute storm.

Robertson sees the first card of the game because he pulls back Callejon.
Napoli have started the second half excellently.
Liverpool counter from the corner through Mane's 50 yard sprint which ends when his pass to Salah is dreadful.
Insigne wants a handball as the ball goes out for a corner. It hits Alexander-Arnold on the arm as he jumps, but it's the one by his side so not a pen.
Lozano is given offside and he wasn't!!!
Di Lorenzo manages to dispossess Mane in the Napoli box.
It's well worth seeing that save again later.
What a save by Adrian!!!! Callejon sends a cross field pass to Insigne and then Rui crosses to Mertens at the far post. He thinks he's scored as he raises his boot to knock in from three yards, but Adrian incredibly manages to dive and tip it over the bar! Stunning save.
Lozano is pushed from behind by Fabinho and has got injured as he fell awkwardly on his lower back.
Insigne is flagged offside after just 20 seconds.

HT: Napoli 0-0 Liverpool!!! Brych blows for HT right on 45 minutes. Liverpool have been a bit better than their opponents in a game which has seen the teams take it turns to put pressure on the other team's goal. Napoli had a goal chalked off for offside early on while Mane and Firmino have come the closest for Klopp's men. The defences also look solid. Join us in 10 minutes for the rest of this one.

Mane is fouled by Fabian.
