Napoli v Lazio live: Maurizio Sarri takes on former club and league leaders

It's all over and Lazio have beaten Europe's in-form side thanks to Vecino's stunning half-volley.

Napoli's star striker has had a game to forget. He helps the visitors waste precious seconds when he's caught offside.

Napoli are on the attack but NDombele is dispossessed and Lazio break out with Cancellieri, who does brilliantly to win a free-kick and run the clock down.

The away side win a free-kick and Milinkovic-Savic goes so close to doubling Lazio's lead, his shot crashing off the bar. There will be five minutes of added time.

Try as they might, Napoli cannot find a way through as Lazio close in on a famous win.

Giovanni Simeone replaces Piotr Zielinski and Tanguy Ndombélé replaces Stanislav Lobotka.

It's all Napoli as the hosts chase an equaliser. Osimhen's header crashes off the bar and sparks a goalmouth scramble. The ball looks destined to find the back of the net but somehow the visitors resist. Napoli claim there's been a handball but the replay proves otherwise.

Napoli turn the ball over and Elmas is given space to drive forward and get a shot away. It's deflected out for a corner, which Lazio are able to eventually clear.

What a goal this is! Kvaratskhelia's header lands on Vecino's right foot but he still has it all to do and unleashes a rocket of a half-volley from 25 yards that gives Meret no chance in goal. Game on!

Osimhen brings down Alberto and earns himself a yellow card.

First change of the game as Pedro replaces Felipe Anderson.

This is more like it from Napoli. This time it comes from the right-hand side as the ball is played into Osimhen, who lays it off for Zielinski but he is unable to find the target.

Zielinski is brought down by Alberto to give Napoli a free-kick just outside the Lazio box. Kvaratskhelia lines it up but his effort sails over the bar. What a waste!

Olivera and Zielinski link up brilliantly to set up Osimhen. The Nigerian gets a shot away from the edge of the box but it's deflected out for a corner.

The Napoli striker takes a sore one as he comes together with Patric. The replay shows the Lazio defender's shoulder connects with Osimhen's face. He's down but is fine to carry on.

Napoli get the game restarted.

The teams are all square at the break. Lazio went closest to opening the scoring early on but that's been the only clear-cut chance of what's been a fairly lacklustre first period.
