"The deal is very advanced," Marcelo London told La Oral Deportiva.
"On Tuesday he'll sign, and we'll be able to say that he's our player. Osvaldo is in perfect condition, and will be Boca's eighth signing.
"He'll come on loan, with a clause that states if Boca play in the semi-final and final of the Copa Libertadores he can play those games."
