Cittadella produced a stunning display in the opening round of the Coppa Italia as they thrashed Potenza 15-0 on Sunday.
The Lega Pro side ran riot in their first competitive game of the new season, scoring 10 goals in the second half alone.
Brescia began life as a Lega Pro side with a stuttering performance against Cremonese, the third-tier club - who count Roberto Baggio, Pep Guardiola and Andrea Pirlo as former stars - needing penalties to progress.
After a goalless 120 minutes, Brescia - who were relegated from Serie B last season - eventually prevailed 4-3 in the shootout, Carlo Crialese missing the decisive penalty for Cremonese.
Lecce's clash with Catanzaro also went to spot kicks.
Despite two misses in the shooutout, Lecce - a Serie A side as recently as 2012 - were able to prevail 3-2 as their opponents lost their nerve from 12 yards.
Francesco Nicastro and Alessandro Gatto were on target in Juve Stabia's 2-0 win over Melfi, while Cosenza came from a goal down to beat Ascoli 2-1, and Foggia needed extra-time to beat Lucchese.
Tuttocuoio, Bassano Virtus, L'Aquila, Sudtirol, and FeralpiSalo also enjoyed success in the opening round, the latter romping to a 5-1 win over Fano.
