Ospreys forwards coach Chris Gibbes called out Treviso for having no desire to play any positive rugby during Friday's PRO12 clash.
The Welsh region comfortably outclassed the visitors, winning 47-10 and scoring seven tries including a double for full-back Dan Evans.
Gibbes suggested the Treviso's only aim was to try and outmuscle the Ospreys upfront, and when that failed that they lacked an inventive approach.
Treviso have won just twice this season in the PRO12 in one of their worst seasons in recent memory.
Dean Budd was shown two yellow cards and Robert Barbieri was also sin-binned as the Italian side's discipline let them down in Swansea.
"I don't think they've come to play positive rugby," said Gibbes.
"I might get my hand slapped, but if you look at the amount of stoppages, ball-in-play time, even scrum platforms, I don't think they've turned up here ready to play a game.
"They've tried to muscle us, that hasn't quite worked, and they've resorted to trying to slow the game down – I don't think that's positive rugby."
