[7] He returned to a recently relegated Flandria in July 2018, prior to immediately leaving on loan once again to Ecuadorian club Delfín.
Riveros made his debut on matchday 4 of the Apertura phase against Unión Comercio; a game in which he did not have a good performance, being criticized for that.
