Napoli boss Walter Mazzarri accepts they're now title contenders.
"We are putting pressure on ourselves, as we always want to do better," said the Coach after their 2-1 win over Cagliari.
"We've got to focus only on us and not think about anything else. Keep your heads down and push on, because it would be a crime to mess up the last few games.
"It wasn't easy to break down Cagliari, who kept the pressure up continually. After the break we managed to create a little more space and were sharper, also as we stepped on to the field with a different spirit.
"However, we've got to be more clinical when we take the lead and not risk throwing away valuable points."
