Manchester United and Wolves are being linked with a possible swoop for winger Douglas Costa.
He did play two games for the Old Lady this season before making the switch.
FIFA rules stipulate a player cannot play for three teams in a single season.
According to Gazzetta dello Sport, FIFA will bend the rules this term due to the COVID-19 pandemic.
Bayern would be happy to let Juve take back Costa, and the Italian club would then look to sell him on in January or the summer.
United and Wolves could be possible destinations, but the player's age, wage demands and injury record could hamper any possible transfer.
