Barcelona, Mingueza's former club, retain 50% of his rights and had hoped to re-sign him on a cut-price deal. However, Liverpool's interest has left Barcelona resigned to missing out on their top target.

FC Barcelona is keeping a close watch on Óscar Mingueza, a right-back for Celta de Vigo, owing to his impressive performance and a relatively low release clause of 20 million euros. Despite facing economic challenges, Barcelona is keen on strengthening their defense and holds a preferential purchase option along with 50% of any future sale of the player. Celta de Vigo's president, Marian Mouriño, has indicated satisfaction with Mingueza's current contract and is open to renegotiating to increase his release clause, aiming to prevent a low-cost exit. Mingueza has demonstrated his commitment to Celta de Vigo's project, which adds uncertainty to the potential transfer.

There are rumors of a possible return to FC Barcelona for Óscar Mingueza, but he is currently negotiating his future with Celta de Vigo.

Marco Garcés, director deportivo del Celta, stated that Barça has a right of first refusal on Mingueza and a percentage of a future sale, but no option to buy. This contradicts the official version from Barça when they closed his transfer to Celta in August 2022, claiming they reserved a buy-back right and 50% of a future sale.
