Néiser Villarreal, a forward for Millonarios and the Colombian U-20 National Team, was linked to several major European clubs. However, due to complications arising from Villarreal signing contracts with three different agents, his transfer has not materialized. The confusion over which agent would receive the commission has stalled the transfer process. Villarreal remains the most valuable player at Millonarios, valued at 2.8 million euros, with his contract expiring in December 2025. He might leave in the next transfer window if the issues are resolved.

Although Villarreal was linked to Atlético de Madrid, the journalist César Augusto Londoño stated that Millonarios is not aware of any deal with Atlético. The player's agent has rejected good offers and is looking to terminate the contract in December to negotiate with another club with Villarreal as a free agent. Currently, Transfermarkt estimates the player's market value at 1.20m euros.
