Napoli captain Marek Hamsik hailed the manner of their win over Roma.
The Azzurri stayed top of the table with the 1-0 triumph.
“It was a very difficult match and we played against a great side," wrote Hamsik on his official site.
“We once again arrived in great shape, remained concentrated to the end and won the game. It's fantastic to win at the Olimpico for the second time in a month (after the 4-1 at Lazio).
“We are only looking at our own position in the table, even if we are very happy to give all we can. This is just the beginning, though, as there is a long season ahead of us.
“Now we must turn our focus immediately to the Champions League, as on Tuesday we take on Manchester City, one of the best sides in Europe."
