Costa, Chuopo-Moting join Bayern on deadline day
Juventus winger Douglas Costa has returned to Bayern Munich for another loan spell, while former PSG attacker Eric Choupo-Moting joins as a free agent on a frantic transfer deadline day.
Costa played for Bayern between 2015 and 2017, initially on loan before joining on a permanent basis.
The 30 year-old made 103 appearances for the Bianconeri across all competitions, scoring 10 goals and winning the Serie A title three times, as well as the Coppa Italia in 2018.
"I am very happy to play for Bayern again," he said. "I had a wonderful time in Munich with many successes and I am sure that we will win titles again now."
Sporting director Hasan Salihamidzic said: "Douglas will strengthen us on the outer flanks that are important for our game. We are now very well staffed with Serge Gnabry, Leroy Sane, Kingsley Coman, Jamal Musiala and Douglas.
"Douglas knows Bayern and will find his way around very quickly."
During his first stint at Bayern, Costa won two Bundesliga titles, the DFB-Pokal and the DFL Supercup, scoring 14 goals in 77 appearances.
He becomes Bayern's third signing in two days following the captures of Eric Maxim Choupo-Moting on a free transfer and Marc Roca from Espanyol for a reported €15million.
Choupo-Moting, who has previously played in the Bundesliga for Hamburg, Nurnberg, Mainz and Schalke, has signed a one-year deal with Hansi Flick's side.
"It's a great feeling to come back to the Bundesliga and then to the biggest club in Germany," he told the club's official website.
"Who wouldn't want to play for Bayern? It's an honour to play for this club. At Bayern, the aim is always to win everything and I am highly motivated to achieve these goals."
As for Juve, it has also completed the capture of Federico Chiesa from Fiorentina on deadlined day.
