Philippe Coutinho had been linked with Paris Saint-Germain in recent months, but the Brazil international will be heading to the Bundesliga.
Bayern Munich have confirmed that Coutinho will join the club on a season-long loan.
The 27-year-old was missing from the Catalan giants' matchday squad to face Athletic Bilbao in the LaLiga opener on Friday night.
Reports in Spain claimed that Barca were looking to use Coutinho as part of a deal to lure Neymar back to Spain, with the latter reportedly set on leaving PSG.
However, those reports were squashed by Coutinho's agent, Kia Joorabchian, who denied he was in the French capital.
"I am not in Paris, I am in London," Joorabchian told Mundo Deportivo. "Reports of me being in Paris discussing Coutinho with PSG are simply false."
