Spezia coach Vincenzo Italiano says Napoli were simply too strong for Saturday's 4-1 defeat.
Napoli were 3-0 up at halftime as they cruised to victory.
“It was a game that started badly and we never recovered. The credit goes to Napoli, as they were so aggressive and didn't allow us to get into any kind of rhythm," Italiano told Sky Italia.
“There's not much we can say, when Napoli play like this, they are more than a handful for any opponent, let alone Spezia. We tried to fight back and to limit them, but they were just too strong."
The pace of Victor Osimhen was a decisive factor, as he scored two goals and assisted another for Hirving Lozano.
“We were too timid and didn't show enough courage when closing Osimhen down."
