In July 2024, the Brazilian club Flamengo transferred 70% of the economic rights of the player Werton to Leixões for a sum of 1 million euros. The initial installment, valued at 175 thousand euros, was scheduled for payment by the Portuguese club in November 2024. Flamengo indicated that they had not received the payment and reached out to Leixões in January 2025 to request the overdue amount. Receiving no response, Flamengo issued a subsequent notification on January 14, setting a 48-hour deadline for the revised amount of 196.7 thousand euros to be settled. With Leixões failing to meet the terms of the agreement, Flamengo has escalated the matter by lodging a formal complaint with FIFA's Dispute Resolution Chamber, seeking the outstanding payment along with interest, penalties, and monetary adjustments.

Werton has been acquired by Leixões from Flamengo. This transfer also led to a significant increase in social media followers for Leixões.

Werton has been officially signed by Leixões from Flamengo. This transfer is independent of the potential acquisition of Leixões by Flamengo.
