Napoli coach Carlo Ancelotti was delighted with their 3-0 win at Udinese.
Dries Mertens struck, along with substitutes Fabian Ruiz and Marko Rog.
“It's another show of our maturity. We had finished on a high before the break for international duty and wanted to start this run on the same level," Ancelotti told DAZN.
“It was a hard-fought game, in some ways a struggle, but an important victory and we got a good response from everyone.
“The clean sheet shows we are starting to rediscover our solidity in defence and the work of the forwards is important too. The collective defensive movement was very good today."
