Lazio coach Maurizio Sarri hit out at Feyenoord fans after their Europa League defeat in Rotterdam.
The result sees Lazio eliminated from the Europa League and dropped into the Europa Conference League playoff.
Sarri said, “There were bags of p**s thrown from the stands down onto the back of the bench. It goes without saying, that is a little irritating."
The coach continued: “I won't even start on the referee. One player had at least seven or eight fouls from behind on our players, but in the end the only yellow cards were to my team.
“As for their goal, there were two fouls in it, not one. It started with a foul on Matteo Cancellieri near my bench, then Patric was clearly pushed from behind at the goalkeeper.
“We expected at the very least for the referee to view it again with VAR."
