Juventus crashed to a humiliating 2-0 defeat at Cagliari on Wednesday days after sealing their ninth consecutive Serie A title.
Cagliari’s 20-year-old forward Luca Gagliano tapped in the opener eight minutes into his first Serie A match, beating veteran Juventus keeper Gianluigi Buffon to score his first top division goal.
And the young Italian then teed up Giovanni Simeone in first half stoppage time to give Cagliari their first win over Juventus in 11 years.
Cristiano Ronaldo missed the chance to keep pace with Serie A’s leading scorer Ciro Immobile, the Portuguese now four goals behind the Lazio forward’s tally of 35 with one match remaining.
It was a worrying performance for Maurizio Sarri’s side, who have won just two of their last seven games, with key forwards Paulo Dybala and Douglas Costa fighting for fitness ahead of the Champions League showdown with Lyon on August 7 in Turin, when they need to overturn a 1-0 first-leg deficit.
In Rome, Immobile moved to within one goal of equalling the Serie A single season scoring record as Lazio beat relegated Brescia 2-0 to stay in the race for second place.
Immobile struck eight minutes from time to close in on Gonzalo Higuain’s record of 36 goals, scored for Napoli in 2015-16.
Lazio are fourth, equal on 78 points with third-placed Atalanta, who beat Parma 2-1 on Tuesday, and one adrift of Inter Milan who are second following their 2-0 win over Napoli.
AC Milan remain four points behind Roma after Zlatan Ibrahimovic scored twice and set up a third in a dominating display against Sampdoria.
The 38-year-old got his head to an Ante Rebic cross within four minutes in Genoa for his fastest goal in the Italian top flight, before nodding the ball across for Hakan Calhanoglu to add the second six minutes after the break.
Turkish winger Calhanoglu provided the cross which allowed Ibrahimovic to add his second of the night.
Leao added a fourth in injury time as Milan extended their unbeaten run to 11 games.
