Lazio coach Simone Inzaghi was delighted with 1-0 defeat of Napoli.
Ciro Immobile proved the matchwinner as Lazio set a new all-time club record beating the nine consecutive triumphs set by Sven-Goran Eriksson in 1998-99.
“I thought we played better in the first half, then Napoli were stronger after the break, so it was a balanced encounter and all came down to the goal," Inzaghi told Sky Sport Italia.
“I think it's all down to the work we did in pre-season, which I thought was fantastic. We started by dropping a few points in Serie A and the Europa League, but we were playing our game and doing what we asked in training.
“So the lads realised their coach was calm and reassured, despite a few critics and some disappointing results, because we all believed in what we were doing and thought the results would come.
“I didn't think we'd win 10 in a row, but I saw good things! I've been complimenting my players for the last three months and telling them to focus on the next match, so I won't change the message now.
“Napoli have had some problems, but they remain a great team and have so much talent at their disposal, this shouldn't be taken for granted."
