Catania coach Walter Zenga has warned Roma to expect an all-out battle today.
"Our aim is to stay in Serie A, so we will play our game the way we always have done," said Zenga, whose Catania need victory to be safe, while Roma also want the three points as they attempt to beat Inter Milan for the title.
Zenga is a former Inter star and represented the club as a goalkeeper from 1982-94, but insists his love for the Nerazzurri plays no part in this match.
"Our destiny only depends on us. That is the fundamental difference between Catania and Roma.
"Even if they win, there is nothing certain in it, whereas with a victory we are sure of our Serie A status. This is already a massive and I would say crucial difference."
In fact, to win the title Roma must beat Catania and hope Inter fail to achieve victory away to Parma.
"We are only counting on ourselves. We are relaxed and will not give up."
