Napoli coach Luciano Spalletti says they must not take anything for granted against Salernitana.
Victory on Sunday will confirm Napoli as champions.
Spalletti said: "You always play for the maximum, with a suit and a whistle on the pitch, with strong players who immediately tell you off if you think differently.
They are guys who can sense the mood around them, and enthusiasm sometimes makes you play games like the one this morning where the ball was spinning at two thousand kilometres an hour.
What they've built up is exciting, there's a reaction from everyone, even you can sense it by seeing how many of you there are today. You work to the best of your possibilities and abilities, without remorse, using all the time you can.
If you love something or someone, the only thing you can dedicate to them is time, that shows how much you love them, and I have dedicated it all to them. With the team we've done our best, we've dedicated as much time as we can since I left.
I'm not even convinced about my work if I don't devote all my time to it, it's a necessity for me in those two hours to do something else to see instead of pictures. It depends on the availability you create for your profession."
