11th place and was the second best team in Europe for 2 of his first 3 seasons. Seems like overperforming to me.
Sarri had all of Ronaldo, Dybala, Higuain in his season here plus was bought 75 mil De Ligt and 30 mil Demiral and scraped scudetto with 83 pts, +34 goal differential, and CL Rof16 exit to 7th place Ligue 1 side Lyon. -7 pts, -6 goal differential, and a round earlier exit in CL to a far worse team.
And you think he was a success and deserved another year
