"Serge won't be there, Manu won't be there," Kompany told reporters, explaining "Manu has rib pain". The 38-year-old goalkeeper failed to take part in training on Friday, and Kompany did not indicate when he would return.
Neuer and Gnabry join Bayern's long injury list, which includes England captain Harry Kane, Joao Palhinha, Josip Stanisic and Hiroki Ito. Almost all of them are going to miss some other matches these weeks.
Kane injured his hamstring in last Saturday's 1-1 draw at Borussia Dortmund and missed the loss to Leverkusen, but returned to individual training on Thursday. "It looks good," Kompany said of Kane's recovery. "The way it's going now, it looks like he could play one or two games in the calendar year if everything goes well."
