Estudiantes face frustration in attempts to keep hold of Marcos Rojo.
Ole says Estudiantes are looking at alternative centre-backs for next season after learning Manchester United's asking price for Rojo.
United's reported £12m asking price was considered 'a bucket of cold water' for the Argentine side.
Estudiantes hope to keep Rojo, but at a cheaper price.
Boca Juniors are also watching developments closely.
