Roma v Napoli live - Pellegrini breaks deadlock for hosts after Politano is sent off

That's as close as they have come. A free-kick from the left wing finds its way to Osimhen at the back post, who overhead kicks it back into the mix before Anguisssa tries to spectacularly backheel it in, but can't make proper contact and it drifts wide.

Another yellow. And then ANOTHER! Is the referee losing his grip a bit here?

First Cristante, then Mourinho. The first for a trip, the second presumably for complaints.

Osimhen goes down clutching his face in the box, but the referee isn't interested and Roma immediately threaten up the other end, but a cross is cut out.

Osimhen is still down in the box...replays show Paredes did catch him with a flailing arm, but that's surely not enough for a spot kick.

Roma are the team asking the questions in attack, and this time it's Zalewski who threatens as he cuts in from the left wing and puts a shot wide.

And another one! This is getting out of hand. That is four posts in a row that have been to tell you about a yellow card.

This time Kristensen goes in the book for throwing an arm up into the face of Kvaratskhelia as he went on a charge upfield. This match hasn't exactly been eye candy so far.

A decent Roma move as Bove finds a gap to spin a ball out wide for Zalewski to throw back in the bix, but it's offside.

Mazzarri is the next name in the referee's notebook - he's clearly made his feelings a bit too clear down there after an unconvincing start from his team.

Former Roma man Juan Jesus makes a good challenge and hopes to spring a counter-attack, but Mourinho's men are ready with about five men back in their own half.

Following that, Paredes and Rui pick up the first bookings of the night.

Di Lorenzo limps off and Roma have a free-kick midway into the Napoli half, but it's repelled before Bove thumps the ball into the stands. Which is impressive, given they are about two kilometres behind the goal at the Olimpico.

Another injury stoppage now as Di Lorenzo goes down following an aerial challenge with Bove. The Napoli captain requires some attention.

Meret comes hurtling out of his box to clear the ball for a throw before Lukaku can get there. Napoli are hanging on a bit at the moment...

Roma so close again! This time Belotti does brilliantly with a turn of pace to get past his marker to the byline and cut the ball across the six-yard box for Bove, but the midfielder's shot is charged down by Meret at point-blank range!

Fantastic save but another huge chance for the young midfielder.

Now THAT'S a chance! Bove sets up the move with a lovely through ball for Lukaku, who holds it up and plays it back to the midfielder.

Bove takes it first time but his dipping effort clips the top of the bar on its way over. By far the closest we've come to a goal!

Cristante has a go from an awkward bobbling ball, but slices his effort miles high and wide. Still, a shot's a shot. And that's the first of the match, I believe...

Rrahmani is on his feet again and Napoli deal with the corner safely without him. As you were.

Rrhamani heads the ball out for a corner, but lands awkwardly and the medics rush on. He's not looking great.

Di Lorenzo whips in a cross from the right, but it's easily dealt with by the Roma defence. Approaching the 15-minute mark and we're yet to have a chance of note here...

Just as I write that, a bit of Napoli pressure. Politano and Anguissa link up nicely to send the winger into the box, but his shot is blocked.

Zalewski tries an acrobatic overhead kick from a second ball on that throw but can't connect properly. Roma have started the brighter here, though.

Roma win a free-kick in a decent position, midway into the Napoli half and five metres from the right touchline.

Paredes puts in the delivery, but it's haeded straight back out for a throw.

Osimhen has gone down and stayed down. The home fans boo their dissaproval, as it looked fairly innocuous. The striker is back on his feet again and it's a drop ball.
