Napoli have signed Uruguay centre-back Miguel Angel Britos from Bologna.
Britos, 25, who made 70 league appearances for Bologna after moving from Montevideo Wanderers in 2008, joins Walter Mazzarri's side for an undisclosed fee.
"I am delighted to have arrived at Napoli,'' said Britos in a press conference. "I`ve come to a big club and here I can make the leap in quality that I always dreamed of. Mazzarri wanted me here and I hope I can soon repay his trust.''
Napoli are also close to completing the acquisition of Argentinian winger Mario Alberto Santana, who is available as a free agent after leaving Fiorentina earlier this summer.
Santana could become Napoli's third signing in the space of 24 hours after the club unveiled Swiss midfielder Gokhan Inler on Monday.
