The 34 year-old Uruguay international held talks with Riquelme about moving to Boca ahead of signing a new 12 month deal with United last week. The veteran arrived last summer on a free transfer from Paris Saint Germain and despite some injury problems, has enjoyed an outstanding first season in England.
He told TNT Sports via Sport-Express: "I think that next year Cavani will be with us.
"He told us himself that he was looking forward to his arrival. The doors are always open for him. His arrival should be associated with the return of the public to the stadiums.
"But today we do not have an audience."
So far this season, Cavani has managed 36 appearances for United, scoring five goals and producing five assists.
Boca Juniors, meanwhile, sit second in the first phase of the Argentine Primera Division in Group B. Boca drew 1-1 with River Plate on Sunday. Riquleme, a former Argentina international, has been vice-president at Boca since 2019.
