Napoli have completed the signings of Velon Behrami and Alessandro Gamberini from Fiorentina.
President Aurelio De Laurentiis confirmed to Radio Marte, the official broadcaster for the club, that the duo had been signed outright.
Switzerland international Behrami, 27, expressed his delight at the switch.
"It's a great feeling arriving at such a great club," he said. "I'm really proud to be at Napoli. Napoli president Aurelio De Laurentiis is a very direct guy and someone who has great objectives. That's infectious as I now want to think big too."
Napoli coach Walter Mazzarri had earlier talked up the players, suggesting 30-year-old defender Gamberini could make a big impact.
"Gamberini is a player who, like Goran Pandev, needs to be re-evaluated," Mazzarri said. "He has some important experience and is an Italian international.
"Behrami is younger, a player who has always done well and has never thrown in the towel. He, like Gamberini, can cover a number of roles. He can play in the middle of midfield and on the wing. He is a player who can be very useful."
