Lazio coach Maurizio Sarri denied claims of pressuring the match officials after victory over Udinese.
Lazio won via a penalty won and converted by Ciro Immobile on 62 minutes.
Udinese staff accused Sarri's coaching team of pressuring the match officials at halftime.
But he later said: "No one spoke to the referee about us during the interval, I didn't even see him.
"On the penalty, if we are all biased I would say that it was also sending off because it was also a clear goal opportunity."
