Find out how all of the action unfolded courtesy of Sports Mole's minute-by-minute updates below.
The opening round of group games has thrown up a few mouth-watering glamour ties this season, and tonight's match is one of them with Liverpool beginning the defence of their crown at a stadium where they were beaten last season. It is the runners-up in Serie A against the runners-up in the Premier League, and it promises to be an enthralling affair.
Kickoff is only five minutes away, so let's have a quick look at the team news before we get started!
SUBS: Zielinski, Elmas, Ghoulam, Ospina, Milik, Maksimovic, Llorente
SUBS: Shaqiri, Kelleher, Gomez, Lovren, Lallana, Oxlade-Chamberlain, Wijnaldum
Both sides have played with clear attacking intent and are looking to get forward whenever possible, they just need to be a bit more clinical in the final third. The defences have also been impressive in fairness.
Mane has also had a good sight of goal when he was released by Henderson into the box, but the angle was against him and he was denied by Meret.
It was Fabian Ruiz who offered the initial threat with a couple of powerful strikes which were beaten away by Adrian, and Lozano then nodded the second rebound home from close range only to be correctly flagged offside.
Ajax 1-0 Lille
Benfica 0-0 RB Leipzig
Chelsea 0-0 Valencia
Dortmund 0-0 Barcelona
Salzburg 5-1 Genk
The dutchman was under pressure and put too much on his pass back to Robertson, playing it straight through for Llorente who was left with only the keeper to beat.
Mertens got the opening goal from the penalty spot in the 82nd minute, and Fernando Llorente added the second to secure the points 10 minutes later.
Thank you for joining Sports Mole for tonight's Champions League clash between Napoli and Liverpool as the hosts score twice late on to seal victory over the holders. I will leave you with our match report, and be sure to stick around for reaction too.
From me, though, it is goodbye for now!
