Napoli managed to beat the Hammers 1-0 win, following a goal from Fabio Quagliarella.
“I can say that we played a great game,” said Zola.
“I told my men we did very well, even if we lost. We were facing one of the best Italian teams. I think the Azzurri will end in the top six next season.
“It was a good test; we improved a lot from the last friendly.”
