Siena have now officially signed Portuguese defender Luis Carlo Novo Neto from Nacional de Madeira.
The deal had been in the works for some time, but was held up by red tape in the last couple of weeks.
Neto had already chosen shirt number 13.
The 24-year-old centre-back had joined Nacional in 2011 after coming up through the youth ranks at Varzim.
