Estigarribia agent admits Juventus future clouded
The midfielder joined Juve last season on-loan from Deportivo Maldonado.
"The boy is very tied to Juventus and it is certainly a destination that he would like," agent Giuseppe Addamiano told TMW.
"But he has other options. River Plate have wanted him for over a year and they know him well - they are moving strongly for him.
"There are other possibilities as well. There is a French club, that will be playing in the Champions League, who are interested and there has been a concrete offer from Spain."
