Sosa arrived in Rio de Janeiro over the weekend to undergo medical tests, which he passed. He then signed the contract and began training with Vasco coach Pedro Emanuel. However, the midfielder will not be able to make his debut for the team against Olimpia on August 12, 2026, as Vasco was unable to register him in time.
This signing is the latest in a series of moves by Vasco in the transfer window, following the arrivals of Paulinho and Facundo Colidio. The team will be looking to make a strong impression in the Copa Sul-Americana, and Sosa's experience and skill will be valuable assets in their quest for success.
