The Italian side travel to Scotland after suffering back-to-back European losses to Northampton Saints - including a 67-0 reverse at Franklin's Gardens last Saturday.
Treviso are still searching for a first GUINNESS PRO12 win of the season, although they did earn a 24-24 draw with reigning champions Leinster in round eight and followed that up by notching three tries against Cardiff Blues.
And while Casellato refuses to blame his players for the manner of the defeat to Northampton, he is keen to see them bounce back in style at BT Murrayfield.
"The responsibility for the Northampton game is ours alone, the staff," Casellato told La Gazzetta Dello Sport.
"Obviously during the week we were not able to transmit the right input to the players. The boys gave it their all and they did what they could but obviously that wasn't enough.
"Now we have a few days to recuperate before we go to Edinburgh next weekend and prove that the Northampton game isn't who Treviso are.
"In the matches that remain this year we have to produce a reaction that shows our pride."
