Paulo Fonseca insists AC Milan's derby victory over rivals Inter is "irrelevant" unless the Rossoneri beat Lecce on Friday.

Milan claimed bragging rights in Derby della Madonnina on Sunday, with Matteo Gabbia's late effort sealing a dramatic 2-1 victory at San Siro.

The Rossoneri subsequently ended a run of six straight defeats against the Nerazzurri stretching back to September 2022, while moving Fonseca's side level on eight points with their rivals.

Three points adrift of leaders Torino, Milan can move top of Serie A with victory over Lecce, who have won just one of their opening five matches this season.

And with his side riding the crest of a wave after beating the reigning Scudetto winners, Fonseca highlighted the importance of ensuring his side do not come crashing back down to earth.

"There are lots of motivations to win tomorrow," he told reporters during his pre-match press conference. 

"For me, it's a dangerous match after the derby. We have to be careful, we can't make any mistakes. We have to win.

"A win in the derby brings confidence, it brings a different atmosphere. But I always try to be balanced. One match can change everything, it helps the players' confidence, too. But it's just one match. If we don't win tomorrow, people will say we could be relegated. 

"For this reason, we have to forget about the derby, focusing on the next game, which is the most important. The atmosphere is positive, we are happy, but it's important to understand that the derby is over, it's irrelevant now.

"It's very, very important [we capitalise on our momentum]. We have to confirm that we are growing. The victory in the derby makes more sense if we also win against Lecce, because we need to start recovering some points."

Roma’s 10 men held out to see off Serie A rivals AC Milan 2-1 at the Stadio Olimpico and secure a place in the Europa League semi-finals.

Leading 1-0 from the first leg, early goals from Gianluca Mancini and Paulo Dybala put the Giallorossi firmly in control of the tie.

Roma defender Zeki Celik was shown a straight red card after 31 minutes for sliding in on Rafael Leao, but AC Milan could not make their advantage count despite a late consolation goal from Matteo Gabbia.

Ahead of the match, Roma had confirmed head coach Daniele De Rossi would remain in charge for “the foreseeable future”, the former midfielder having overseen an upturn in fortunes since taking over in January after Jose Mourinho was sacked.

Mancini – whose goal had settled the first leg at the San Siro – opened the scoring in the 12th minute.

Roma captain Lorenzo Pellegrini collected the ball just outside the box and curled a shot against the far post. Mancini was first to the rebound, knocking it in from 10 yards.

AC Milan went in search of a way back as Ruben Loftus-Cheek’s angled drive bounced up off the ground and deflected onto the crossbar.

Roma doubled their lead in the 22nd minute.

Romelu Lukaku showed great strength to barge past Gabbia and into the left side of the penalty area. Although the Milan defender recovered to stab Lukaku’s cross away, the ball fell to Dybala, who curled it into the far bottom corner.

Belgian forward Lukaku then sustained an injury and was replaced by Tammy Abraham in the 29th minute.

Roma found themselves down to 10 men just after the half-hour mark when Celik slid in on Leao as the Portuguese forward sprinted away down the left and was shown a straight red card by Polish referee Szymon Marciniak.

The visitors were soon claiming a penalty when the ball bounced around a crowded penalty area and looked to have hit Mancini on the hand.

However, after reviewing the incident on the pitchside monitor, the referee ruled the ball had struck Olivier Giroud’s hand first.

Dybala was also forced off through injury just before half-time, with Diego Llorente coming on.

Roma, who have climbed from ninth to fifth in Serie A under De Rossi, were content to allow Milan plenty of possession but without really stretching the home defensive line.

The Giallorossi looked to hit Milan on the counter, with Leonardo Spinazzola played clear down the left but his low angled drive was pushed away by Mike Maignan.

On the hour, Leao then cut inside to pull the ball back for Luka Jovic but his shot from 10 yards was straight at Roma goalkeeper Mile Svilar.

Roma winger Stephan El Shaarawy got away down the right and sent in a cross which Abraham first tried to flick goalwards with a backheel – and then blazed the loose ball over.

Milan continued to struggle to down Roma before eventually scoring a late consolation when defender Gabbia headed in from Leao’s cross with five minutes left.

In stoppage time, Milan defender Theo Hernandez was initially sent off for a foul on El Shaarawy – only for the referee to overturn his decision after taking another look on the monitor and show a yellow card instead.

Luka Jovic made the difference for AC Milan one minute after coming on as an 80th-minute substitute with the winning strike in their 3-2 Serie A victory at Frosinone.

Olivier Giroud nodded in the opener which was cancelled out before the break by Matias Soule’s penalty, but Luca Mazzitelli fired the hosts in front after half-time.

The sides were back on level terms when Matteo Gabbia, assisted by Giroud, found the back of the net with a diving header before Serbia striker Jovic wrapped up the win.

The result sees AC Milan – in third – move to within four points of second-placed Juventus, having played one more game, while Serie A leaders Inter Milan have two games on hand over Stefano Pioli’s men.

There was a chance inside the first minute for Soule, who fired the ball over the crossbar, as the hosts piled on more pressure in the opening exchanges.

Yet it was the visitors who soon settled in and took the lead in the 17th minute, when Giroud connected with Rafael Leao’s pinpoint cross and cushioned the opener into the bottom right.

Milan goalkeeper Mike Maignan had only just made his first save, tipping Demba Seck’s effort over the crossbar, when Leao was punished for a handball at the right edge of his side’s 18-yard box.

Milan protested, but the penalty was ultimately upheld after a VAR check and Soule stepped up to the spot and fired past Maignan, who moved in the right direction but could not make the stop.

The period with electric pace slowed only briefly when Giroud appeared to tweak his ankle but was deemed fit to continue and soon came painstakingly close to picking up an assist, his delivery across the face of goal from a tight angle narrowly evading both the head of Yacine Adli and a diving Leao.

The hosts wanted Christian Pulisic charged with another handball, but the penalty shout was waived off, and Tijjani Reijnders was unable to break the deadlock when he nodded straight at Stefano Turati.

The Frosinone goalkeeper was forced into a nervy save deep in first-half stoppage time, reacting quickly after Leao’s effort took a dangerous deflection off Caleb Okoli and flew dangerously toward the far corner – Turati just able to stretch his hand out for the stop.

The hosts took the lead in the 65th minute, Soule slipping the ball to Mazzitelli, who came up the middle before handing his side the advantage with a low finish.

The home support had barely finished celebrating when Adli, from a corner, sent a cross to Giroud, who nodded towards the ball in the direction of Gabbia, who drew the sides level with a diving header.

Pioli brought in Jovic for Christian Pulisic in the 80th minute, a decision that paid off instantly when the Serbia striker pounced on a loose ball that had bounced off grounded Frosinone defender Simone Romagnoli and fired home.
