The 22-year-old attacker signed a three-year contract with the Bavarian side in June but will spend the 2017-18 season with another Bundesliga team
Bayern Munich have allowed Serge Gnabry to join Hoffenheim on loan for a season, confirming it was at the winger's request.
Gnabry had been linked to Hoffenheim when he activated an exit clause in his contract with Werder Bremen, and RB Leipzig expressed an interest too.
The 22-year-old joined the Bundesliga champions instead, but CEO Karl-Heinz Rummenigge admitted on Thursday that he wanted a season on loan.
Bayern have now confirmed that the former Arsenal player will make the move to the side that finished fourth in the German top flight last term.
