Stop talking rubbish! That should be a 1-4-3-3 with Totti,Del Piero and Vieri all playing as forwards. Its quite an attacking formation actually.
What Trappattoni plays is the catenaccio system. Source http://en.wikipedia.org/wiki/Catenaccio
"Italy's previous coaches, Cesare Maldini and Giovanni Trapattoni, used the catenaccio at international heights, and have all failed to reach the top"
