Simone Pesce replaced Joseph Desire Job in the first-half, and after five minutes on the pitch he was sent-off after he was booked for the second time.
Tesser said: “The referee only whistled in one direction today, especially when it came to handing out cards. We’re missing a lot of points, too many, this season because of refereeing errors.
“This defeat came from Simone Pesce’s exaggerated sending off and a clear penalty on Michelangelo Minieri that wasn’t given. It’s not easy to keep going like this and, not to look for an alibi, we’d be a lot higher up the table without these mistakes from the officials.”
