Asked about joining Napoli, Toni replied: "It wouldn't be bad. Quagliarella is a great player and everyone knows about Lavezzi.
"Napoli is an important place. The President wants big things. The fans are fantastic. We'll see what happens. It's too soon to talk about it."
Reflecting on his time in Germany, Toni said: "In spite of everything it's been positive. In two years I scored 60 goals. But now it would be wonderful to return to Italy.
"It's the last World Cup that I can play in. I have won one as a protagonist and I would like to do it again."
