Roberto Donadoni trusts Cagliari can follow the upset that saw Roma thrashed 5-1 earlier this season.
“When you face a team that is technically more gifted, then you need to play over 100 per cent, so even more as a unit,” explained the Coach.
“The fact remains it is XI against XI and we'll give it our all. I have not yet decided if Andrea Cossu or Nene will start, as both are equal in my view.”
Roma will be out for revenge, having been hammered 5-1 in Sardinia earlier this term, although at the time Pierpaolo Bisoli was on the Cagliari bench.
“It's true that this will be a difficult game and Roma are extremely motivated, but we will give it everything we've got against a side with great quality and champions,” concluded Donadoni.
