Leicester director of rugby Richard Cockerill admits he was surprised at the penalty try that went against his side at Stadio di Monigo on Saturday.
Irish referee Alain Rolland awarded Treviso the decision on 30 minutes when a first-phase driving maul was collapsed ten metres from the line.
"I felt the referee was against us a fair bit. I doubt I will ever see a more bizarre penalty try against us," Cockerill told the Leicester Mercury.
"I was just amazed. I have been playing the game for 30 years and coaching for 10 years and I have never seen anything like it in my whole life.
"If that (try) had been given for us, I would have sat there in embarrassment.
"It's all down to interpretations but what about the series of scrums at the end where we have to have several scrums to get our reward?"
Cockerill's last comment referred to pressure on Treviso's line that ultimately resulted in a penalty try for Leicester, which won the game and kept their hopes of topping Pool 2 alive.
