From there, he moved to Bayern Munich in 2015. A loan deal to Juventus was turned permanent in 2018 and he has since returned to his roots with a loan back to Gremio in 2021.
Costa is known as a master playmaker and a tricky player to stop and has played for high-profile managers including Carlo Ancelotti, Pep Guardiola and Max Allegri.
Injuries have blighted Costa's career, but he managed to secure a move to the MLS with LA Galaxy in 2022.
Career at Bayern Munich
After winning eleven trophies at Shakhtar Donetsk between 2010 and 2014, Costa became hot property.
Costa signed for Bayern Munich ahead of the 2015/16 season, with the transfer announced on July 1, 2015. At the time, Bayern were coached by Pep Guardiola. He signed a five-year contract with the German giants.
Costa finished 2015/16 with seven goals and 18 assists in 43 matches across all competitions. However, when Ancelotti replaced Guardiola, he fell out of favour, with Franck Ribery preferred.
Costa's relationship with the Bayern hierarchy soured somewhat during the 2016/17 season, exacerbated by a war of words with club president Uli Hoeness.
"Costa didn't work out because he was quite a mercenary whose character we didn't like," Hoeness told Frankenpost after Costa left Bayern to spend the 2017/18 season on loan at Juventus. That move would later be made permanent.
Costa, by contrast, claims he did not leave Bayern for money, but rather sporting reasons.
Few would have envisioned then that Costa would return to Bayern on loan from Juventus three years later. According to quotes attributed to Costa, the issues between he and Hoeness during the winger's first spell did not cause long-term animosity between the duo.
Despite his difficulties at Bayern during the 2016/17 season, Costa was part of a squad that won the Bundesliga title again under the guidance of Ancelotti.
Juventus years
Although they were knocked out of the UEFA Champions League in the quarter-finals by eventual champions Real Madrid, Costa did enough to secure a permanent move.
Allegri departed at the end of 2018/19 despite Juve's Serie A triumph and Costa came under the tutelage of Maurizio Sarri for 2019/20. He found life under the former Napoli boss frustrating in terms of playing time, with injuries playing a major role in his lack of minutes.
With playing time significantly reduced in 2018/19 and in 2019/20, Costa took a loan move back to Bayern in 2020, but with that too not able to reignite his career, the Brazilian was loaned back to his native country to Gremio, where spent the 2021/22 season.
After a half season at Gremio, he joined MLS side LA Galaxy in Feb 2022 on loan, before making the move permanent for the 2023 season.
He made 51 appearances for Galaxy and scored eight goals before he left the club at the end of the campaign.
International career with Brazil
Costa's international career showed promise from a young age as he won the Under-20 South American Championship with Brazil in 2009.
Personal life
Costa is in a relationship with Nathalia Felix.
Net worth
Douglas Costa's net worth is reportedly around £58million.
