"The Napoli clash on Sunday is decisive for us and we will have to play with guts and determination," Semeraro told Radio Marte Sport Live.
Roberto Donadoni will be on the Napoli bench and Semeraro has great respect for his adversary.
"I rate Donadoni highly," he said. "Before he took the Azzurri job he was close to coming to Lecce. We spoke and nearly agreed a deal."
