UAR president Carlos Araujo confirmed the talks during his visit to Australia this week for a meeting of the southern hemisphere Sanzar body which runs the Rugby Championship.
"To take this match to London is something very important for the UAR and Argentine rugby," Araujo was quoted as saying by the UAR.
"That our national team could be the home team at that magnificent stadium speaks of the recognition they have and the great standing they currently have in world rugby."
