Athletico Paranaense submitted a formal offer of around €2.5 million to Estrela da Amadora for the signing of Nigerian winger Abraham Marcus. The proposal was rejected for financial reasons, as Estrela da Amadora would have only received 60 percent of the amount because FC Porto possesses the other 40 percent of the player's economic rights. From a sporting perspective, Marcus is considered an essential player for the remainder of the season as the club's primary goal is to remain in the top division.
