AC Milan kept up the pressure on local rivals Inter Milan in the Serie A title race with a 3-1 win over Roma on Thursday, while a coronavirus cloud hangs over the league with four of 10 matches to be left unplayed.
Stefano Pioli's Milan are just one point behind champions and league leaders Inter after two early goals from Olivier Giroud and Junior Messias and a late strike from Rafael Leao won an entertaining contest at the San Siro.
However Inter were the first team on Thursday to have their match abandoned at half-time after Bologna were banned from playing to keep a Covid cluster at the club under control.
Regardless it was a big win for Milan, who were missing their two starting centre-backs Simon Kjaer and Fikayo Tomori and a host of other players to Covid infections or the Africa Cup of Nations, but could have scored more after also striking the woodwork twice.
They are six points ahead of third-placed Napoli, who take on Juventus in the day's late match, after holding off significant Roma pressure after Tammy Abraham pulled a goal back for the away side shortly before the break.
Leao struck the crucial third eight minutes from the end after Roma, already down to 10 following the 75th-minute sending off of Rick Karsdorp, had gone close through Abraham and Henrikh Mkhitaryan.
Roma finished the match down with nine men when Gianluca Mancini picked up a second yellow card and gave away a stoppage-time penalty for a foul on Leao, but Zlatan Ibrahimovic's spot-kick was well-saved by Rui Patricio.
Jose Mourinho's team are six points from the Champions League places alongside Lazio, who could only draw 3-3 with Empoli.
Sergej Milinkovic-Savic nodded home his second of the game in the 93rd minute of a thrilling match at the Stadio Olimpico to snatch a draw for the hosts which leaves them in eighth.
"We want to finish in the top four. It's going to be hard as we are some way away but there are still lots of matches to play," the 26-year-old told DAZN.
Maurizio Sarri's side are four points and one place ahead of promoted Empoli, who thought they were set to come away with another big away win after victories at Juventus and Napoli this season before Milinkovic-Savic struck.
The strange spectacle of teams turning up for fixtures they knew would not be played returned to Serie A after local health authorities (Azienda Sanitaria Locale, or ASL) barred Bologna, Torino, Salernitana and Udinese from playing their matches.
Earlier Serie A released a new protocol which insisted on teams playing matches as long as they had 13 players (including one goalkeeper) available who were born before December 31 2003, otherwise they would be handed a 3-0 defeat and be docked a point.
However figures from across the game have bemoaned the inconsistent decision making affecting teams who are left in the hands of the ASLs, bodies that answer to regional governments and act independently of one another.
"We're in the hands of 20 regions and what is considered a cluster in one isn't in another. If the decision comes from the ASL then it's hard to make a protocol (for the whole league)," said Sarri.
Later on Thursday regional affairs minister Mariastella Gelmini said there would be a meeting between the government, regions and Serie A on Wednesday with the objective of "ensuring uniformity" in the league.
The big match of the weekend between Juventus and Napoli will be played in Turin later despite the away side being battered by Covid cases, including to coach Luciano Spalletti.
However Napoli have put Piotr Zielinski, Amir Rrahmani and Stanislav Lobotka in their starting line-up despite the Turin ASL saying the trio had to isolate after travelling north as they had been in close contact with the club's positive players.
