Tuttosport claims Roberto Soriano was slapped by angry Sampdoria ultras after their fourth consecutive defeat.
The Turin-based newspaper made the allegations following Sunday’s 3-1 home loss to Sassuolo.
According to Tuttosport, chief ultras waited for the team to emerge from the locker room after the game at Marassi in order to discuss the situation.
It became increasingly tense until one of the ultras reportedly slapped Soriano across the face.
So far Sampdoria have not released any statement to confirm or deny the report.
