Italian champions Napoli confirmed on Monday the signing of Brazilian defender Natan two weeks before they open their Serie A title defence.

The 22-year-old arrives from Brazilian club RB Bragantino on a deal worth a reported 10 million euros ($11m).

No details were given concerning the duration of the Brazilian Under-21 international's contract.

His arrival comes after South Korean Kim Min-jae, voted top defender in Serie A last season after helping the club win their first league title in over three decades, left for Bayern Munich on a 50-million-euro deal.

Napoli open their campaign on August 19 at Frosinone.
