Napoli coach Maurizio Sarri says his side deserved to take all three points after a hard-fought 2-1 win against Fiorentina.
The Partenopei were six points behind the leaders before the game but they cut the gap to only three points after Lorenzo Insigne and Gonzalo Higuain were again on target.
They face Chievo away from home next week in the Serie A.
"It was a victory registered thanks to our mental strength," Sarri told reporters.
"I asked our supporters to be the 12th man and they were fantastic. In the first half we struggled and maybe the international break was a reason for this.
"But in the second half we played at our usual pace, giving little or nothing away to register a well-deserved victory.
"Winning this game is not enough, we need to be consistent. There is still a long way to go and at the moment we're focused on Thursday's game in Denmark [against FC Midtjylland]."
