Chris Cusiter insists Scotland are focused on beating Italy and not the possibility of ending up with the Six Nations wooden spoon.
The Scots head to Rome this weekend still looking for their first win of the tournament and will face an Italian side who have also failed to record a victory.
Scotland kicked of their campaign with a 13-6 defeat to England at Murrayfield but that is as close as they have come to winning a match.
Wales were far too good at the Millennium Stadium and ran out winners by 27 points to 13, while France took care of them 23-17.
Ireland scored four tries to thrash the Scots 32-14 in Dublin and so the search goes on for their first triumph in 2012.
But Cusiter, who will start on the bench at the Stadio Olimpico, has made it clear that the possibility of losing to the Azzurri has not been mentioned in training.
"We don't talk about that," he told BBC Scotland. "We talk about winning this game. It's the last game, we've not won thus far. It's the last opportunity and it's a huge game we're focused on winning."
Italy were beaten 30-12 by France but narrowly missed out on glory against England as Stuart Lancaster's men came back to earn a 19-15 win in Rome.
Ireland scored five tries in a 42-10 thrashing of the Italians in Dublin before Wales dealt with them ruthlessly in Cardiff.
Despite the fact they they have failed to win any of the matches and are the perennial bottom nation in the competition, Cusiter feels it would be folly for the Scots to take them too lightly on Saturday.
"We're aware of how tough it will be to win over there, how much improvement Italy have made - particularly looking at their last game against Wales," he added. "Defensively, they're very, very strong."
