"We played the whole game with a certain intensity and got a prestigious result, as Villarreal never gave up and really put up a fight," said the Slovakian.
"We are in the Napoli history books, but want to do even more. Tonight we proved that we are up to the task.
"We didn't let our heads drop when we heard about City taking the lead, nor when Walter Mazzarri was sent off. We fired ourselves up and after Gokhan Inler's goal, we truly believed.
"I am also very happy with my goal. I bet with my best friends that I'd grow a moustache if we won! So many fans came with us here, it felt like we were playing at home."
