Lazio and Roma have played out a goalless draw at the Stadio Olimpico to remain level on points in the Serie A table.
Neither side could find a way through in an intense but shot-shy Derby della Capitale showdown, managing a combined two attempts on target across the 90 minutes.
The visitors will arguably be the more disappointed not to have come away with victory, having had a man advantage for the final 10 minutes after Stefan Radu was dismissed.
Roma's league form has been underwhelming over the past fortnight, but the stunning 3-0 win over Barcelona in midweek gave them a huge boost heading into the final stretch of the campaign.
Radja Nainggolan found Bruno Peres with his searching pass and the resulting shot came back off the upright in a let-off for the hosts.
Lazio had the odd sight of goal in the opening 45 minutes, too, with Marco Parolo bursting through but scuffing his effort
A dangerous delivery from Aleksandar Kolarov was crying out for a Roma player to help the ball over the line, but Peres's earlier shot would prove to be the closest either side came to netting a goal in the first half.
Lazio failed to make the most of a big chance as Senad Lulic took too long on the ball when he had a few teammates well positioned alongside him.
Ciro Immobile then flashed one across the face of goal and Cengiz Under was unlucky with his half-volley sailing over the crossbar.
Just when the Biancocelesti were building up a head of steam, with Luis Alberto skimming the upright from his long-range drive, they were reduced to 10 men as Radu pulled back Under to receive a second yellow card.
Roma could have snatched it late on, only for Edin Dzeko to see one header saved, another hit the bar and a third follow-up attempt end wide.
