"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.
"We are relaxed because we have prepared for this match well, with great focus and respect for a team that has picked up 81 points this season. However, there is another side that has gathered 82 points and is out in front."
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.
"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."
"We are only counting on ourselves. We are relaxed and will not give up."
