Atalanta coach Gian Pero Gasperini clashed with Fiorentina officials at the end of last night's 1-1 draw at the Stadio Franchi.
TMW says the incident occured outside the away dressing room when Fiorentina chief Daniele Prade reportedly insulted Gasperini, which led to the row.
Afterwards, however, Gasperini shrugged off the incident in his presser.
He said: "What happened in the tunnel at the end of the game? I was fine, I was up on my feet.
"Nothing happened."
