Harold Santiago Mosquera is not expected to continue at Cerro Porteño, even though he has a contract with the club until December 2027. It is reported that his decision to leave is due to difficulties with adaptation and a lack of playing time under coach Ariel Holan, which led to his exclusion from the Copa Libertadores squad. His representatives are seeking a negotiated exit that includes financial compensation for the Paraguayan team. Three Colombian clubs are interested and were later identified as Junior, Millonarios, and Independiente Medellín. Junior is supposedly willing to pursue a permanent purchase, an option that would be more attractive to Cerro Porteño, while the other candidates are said to be inclined towards a loan with a fee. The potential transfer is considered a rumor, as there have been no official confirmations. The 31-year-old Colombian winger joined Cerro Porteño in January 2026, and his current market value is €500k, according to Transfermarkt.
