Jose Mourinho, the manager of Roma, faced a chorus of boos at the San Siro prior to their 3-1 loss against AC Milan on Sunday.
Despite Leandro Paredes opening the scoring for Roma from the penalty spot, goals from Yacine Adli, Olivier Giroud, and Theo Hernandez turned the game around.
This defeat further increases the pressure on Mourinho, as Roma now sits in ninth place.
Although serving a touchline ban due to receiving red cards in their last two matches, Mourinho was still subjected to boos when his image appeared on the big screen while watching from the stands.
With his contract set to expire in June, it is widely anticipated that the former Chelsea and Real Madrid boss will depart the Italian capital before then.
