Napoli secured a spot in next season's Champions League after defeating Pisa 3-0 on May 17. The win took Napoli to 73 points, five clear of Como with one match remaining in Serie A [1, 2, 3, 4]. Napoli's goals came from Scott McTominay, Amir Rrahmani, and Rasmus Hojlund [1, 2, 3, 4]. Their title defence had ended earlier this month when Inter Milan secured the Scudetto [1, 3].

Juventus suffered a 2-0 defeat at home against a resilient Fiorentina side reduced to 10 men for most of the match after Luca Ranieri was sent off for protesting a goal decision. The loss dropped Juventus from third to sixth place on 68 points, level with fifth-placed Como but losing out on head-to-head encounter [1, 3, 4].

Meanwhile, AS Roma edged Lazio 2-0 in a heated derby also played on May 17, with Gianluca Mancini scoring both goals. The match turned chaotic after Mancini's second goal, sparking a brawl that resulted in red cards for Lazio's Wesley and Nicolo Rovella, leaving both teams down to 10 players [1, 2, 3, 4]. Roma moved to fourth place with 70 points, tied on points with AC Milan but behind them on head-to-head [1, 2, 3, 4]. The Guardian noted Roma "took a huge step towards returning to the Champions League" with the derby win [2].

AC Milan also won their fixture on May 17, beating Genoa 2-1 to climb to third position on 70 points [1, 2, 3, 4].

The final day of Serie A is scheduled for May 24, when the last two Champions League qualification spots will be decided [1, 2, 3].
