Milan's shaky start puts Paulo Fonseca under pressure ahead of Lazio clash
Milan, last season's runners-up, secured a dramatic late draw against Torino with two goals in the dying moments, but then suffered a disappointing 2-1 defeat to promoted Parma.
Their poor start to the season has left supporters questioning the vision of the Portuguese coach, who was appointed in the close season to replace Stefano Pioli.
Milan will face an unpredictable Lazio side that began the season with a comfortable victory over Venezia, only to lose at Udinese in the following round.
Fonseca will have decisions to make in defence after his side conceded four goals in 180 minutes against supposedly weaker Serie A sides.
New signing Strahinja Pavlovic, who was one of the few bright spots in the last match against Parma, is likely to keep his place over Malick Thiaw, who has faced criticism and is dealing with an ankle injury.
Juventus, under the guidance of new coach Thiago Motta, have made an excellent start to the Serie A season and are the only team with a perfect record after two matches, following decisive 3-0 victories against Hellas Verona and Como.
However, they are set to face their first significant test of the season on Sunday when Daniele De Rossi's AS Roma visit Allianz Stadium on Sunday.
Roma, like Milan, have made an underwhelming start, securing one point from their first two matches, including a disappointing home defeat against Empoli.
Champions Inter Milan will face Atalanta on Friday at home, with captain and key striker Lautaro Martinez's condition improving after a muscle problem. However, Italian media reports suggest he is unlikely to start the match as he has not completely recovered.
Antonio Conte's Napoli suffered a difficult start to the season, losing 3-0 at Hellas Verona, but bounced back with a convincing victory over Bologna in the last round and face Parma on Saturday.
