The Serie B play-out went ahead despite Piacenza's demand to pull out and the first leg ended in a draw with Albinoleffe.
One of these two sides will go down into Lega Pro with the already relegated Triestina, Frosinone and Portogruaro.
Piacenza had asked for last night's match to be postponed until the serious match-fixing allegations in the betting scandal reached a conclusion, but the FIGC ruled they must go ahead.
It was an entertaining enough first half and Guzman went closest when his free kick hit the woodwork for Piacenza.
Felice Piccolo had the chance to win it late on, but blasted over an open goal.
It ended 0-0, so all goes down to the second leg in Bergamo. Due to their superior record during the season, Albinoleffe will avoid relegation as long as they don't lose that game.
