During the summer 2023 transfer window, Santos attracted interest from Benfica, who had an offer in the region of €5 million accepted by Estoril for the right-back. However, Sporting CP invoked an "anti-rival" clause inserted into Santos' contract when he joined Estoril, which stated that the Lions were owed €20 million if the player was sold to Benfica or Porto; for that reason, the move collapsed.
