According to Di Marzio the Rossoneri have finished negotiations with the centre-back and club Atletico Lanus. The agreed upon deal is for a season long loan with an option to make permanent for €8.5 million.
Gustavo is 50% owned by Paraguayan club Libertad, but Lanus has agreed to buyout the rest of his stake with the €8.5 million.
The 23 year old has made 63 appearances in two season with Lanus as well as 16 appearances for Paraguay.
