Bayern Munich president Uli Hoeness said the Bundesliga champions will know more about Niko Kovac's replacement in three weeks.
Head coach Kovac departed following Saturday's humiliating 5-1 loss to Eintracht Frankfurt, which left Bayern fourth in the table and four points off the pace.
The departure ended a 16-month stay for Kovac, who won the league and DFB-Pokal last campaign before experiencing an up-and-down start to this season.
