Riveiro has been heavily linked with a move to Al Ahly, a team he beat in Group C of the 2024/25 Caf Champions League; it ended 0-0 at Orlando Stadium before Bucs won 2-1 in Cairo.
Pirates' physical trainer Carlos Nodar Paz could reportedly join Riveiro in North Africa as a member of Al Ahly's new technical team, having joined the Buccaneers prior to the start of this season.
The Egyptian outfit opted to part ways with Marcel Koller, and contact has been reportedly made with Riveiro's agent.
Having won five trophies with Pirates in Mzansi and helped push Masandawana for the Premier Soccer League crown, the Spaniard is among the highly rated tacticians in Africa.
