Bologna crashed out of the Coppa Italia after a humiliating 3-0 home defeat to Cittadella, but Simone Verdi was sent off within five minutes.
It was a strong line-up from Coach Roberto Donadoni, but their Third Round tie was inevitably ruined almost as soon as it had begun.
Verdi lashed out with an elbow on Pezzi after just five minutes and a red card was the only option, especially as the Cittadella player then had to be substituted.
Cittadella broke through after 20 minutes with Kouame, then just before the break Pasa waltzed round Antonio Mirante to deposit into an empty net.
It was 3-0 by half-time with Litteri finishing off a team move and dooming Bologna to an early exit.
Cittadella will face Spal or Renate in the Fourth Round in November.
Bologna 0-3 Cittadella
Kouame 20 (C), Pasa 40 (C), Litteri 44 (C)
Sent off: Verdi 5 (B)
