Mascara joined Napoli yesterday afternoon.
"At Catania, I leave my heart," the striker told Tuttomercatoweb. "I lived through six wonderful years at the club.
"I want to thank the president [Antonino] Pulvirenti and director [Pietro] Lo Monaco who plucked me from obscurity, brought me to the club , raised me like a child and developed me into the footballer I am today.
"For this, I say thank you."
Mascara is also dreaming of winning the Scudetto with his new side.
"It doesn't cost to dream about winning it," he concluded.
