This was confirmed by a photo that came out after the match between Salernitana and Verona, and was shared by many European media. In the photo, a Salernitana and a Verona player are sitting on the stairs eating pizza. 

It is not that the match was peaceful, it was decided by a goal in the 94th minute, in favor of Salernitana, for the final 2-1, and in the 98th minute there was also a red card. Despite all the sparks on the pitch, Federico Bonazzoli and Simone Verdi sat on the steps and shared a pizza. The story is that Verdi, who is now in the Verona camp and made his debut in September, spent the spring half-season playing for Salernitana on loan, so he must have felt at home.
