AÂ half back combination of Justin Marshall and Gavin Henson has been selected by coach Lyn Jones.
“I was pleased with last week’s performance as the result was never the foregone conclusion that was presented by some commentators,” he said.
“We got the upper hand early on and stayed on top of our game until things were put to bed; the threat presented by Calvisano was fully nullified. Having said that, Calvisano finished the game strongly and they will take confidence from their second half performance, whilst we were disappointed to have conceded three tries.
“Friday’s game will present another challenge to the players and they will again need to be professional in order to deal with the Italian threat. We are now in the middle of an extremely intensive period and it is important we maintain a momentum to get us through this period.”
The Ospreys are eyeing a place in the final eight and, should they earn a bonus point and a victory against Calvisano, they would then have 14 points and be level with current Pool leaders Stade Francais Paris – should Sale Sharks exact revenge over the French side and deny them a bonus point in the process.
