Douglas Costa, the former Brazil winger and star of clubs like Juventus and Bayern Munich, has signed a two-year deal with Sydney FC, marking a significant boost for the A-League. At 33, Costa aims to revive his career after a challenging time with Fluminense, where he failed to score in 22 appearances. Sydney FC Chairman Scott Barlow described the signing as a 'massive coup' that could attract more attention and commercial opportunities to the A-League, which has faced financial challenges. Costa, who boasts a career trophy count of 24, is set to debut on September 19 against Eastern FC in the AFC Asian Champions League 2. He has expressed his ambition to win more titles and elevate the game in Australia, emphasizing his excitement to engage with fans and the local community. With over 13 million social media followers, Costa's presence is expected to significantly enhance the profile of Sydney FC and the league.
