AS Roma moved into fifth place in Serie A with a 2-1 win over AC Milan at the Stadio Olimpico on Sunday to continue the visitors' crisis.
Edin Dzeko headed the hosts in front in the first half before Theo Hernandez drew Milan level after the break.
Nicolo Zaniolo struck the winner after 59 minutes to send Roma above Cagliari into fifth on 16 points, one behind Napoli in the fourth and final Champions League spot.
"The players put in a good performance and fought hard, but it's not easy at the moment to play three games in a week, so they really deserved this," Roma coach Paulo Fonseca told Sky Sport Italia.
"Zaniolo had a great game, scored an important goal for us and we have three very, very important points for the team."
Stefano Pioli has picked up one point from his first two games since succeeding the sacked Marco Giampaolo as Milan coach, a 2-2 draw with Lecce on his debut at San Siro.
His side are 12th with 10 points, having won just one of their last six games.
"I expected more," Pioli said.
"Over the two games, we frankly gave our contribution to the failed victories. We made mistakes that were too obvious for a club of our status."
A lively and entertaining encounter was characterised by defensive errors that led to all three goals.
Dzeko was left completely unmarked to power a header home at the back post from a Jordan Veretout corner.
Milan levelled 10 minutes into the second half as Hernandez was afforded the time and space to gather Davide Calabria's cross and fire a finish past Pau Lopez.
But the hosts were back in front just four minutes later when Calabria gave the ball away cheaply and Zaniolo fired in a shot from the edge of the area.
