Lazio coach Maurizio Sarri was angered by ref Craig Pawson after their Europa Conference League playoff win against CFR Cluj.
Lazio won 1-0, with Patric being sent off for Lazio. Ciro Immobile struck the winner for the Romans.
“The only thing I can say is that it's unthinkable that he officiates at a European level," Sarri told DAZN.
“Immobile scored a difficult goal, but it's the house special. I hope it will contribute to getting some fog out of his head. On a night when everything seemed to be going in the wrong direction, we obtained an acceptable result.
“This is a referee who can't go around Europe to officiate games, he's absolutely unfit. He altered the game with a red card which wasn't a clear scoring opportunity and continued with some shocking yellow cards. I hope he is just a poor referee."
