Lazio ultras display banner against Gianluca Mancini: “Asshole of Rome.”

Lazio ultras did not take kindly to Gianluca Mancini’s post-derby celebration.

The Roma defender was caught waving a flag with Lazio colors and a rat displayed on it.

Following this episode, Mancini received a fine from the Serie A Sporting Judge.

However, the sage is far from over as a group of Lazio ultras from Curva Nord produced a banner with a clear message to the Giallorossi centreback.

“Mancini asshole of Rome,” read the banner displayed near Ponte Milvio with the ultras’ signature.
