Thomas Muller admits his concerns over Bayern Munich's slump in form have been impossible to ignore while on Germany duty.
The Bundesliga champions were thumped 3-0 by Borussia Monchengladbach last weekend as their alarming winless run extended to four matches in all competitions.
That run also includes a draw against Ajax in the Champions League, and a draw to Augsburg and a loss to Hertha Berlin in the Bundesliga.
Speculation already surrounds Niko Kovac's future, with senior players reportedly doubting the new head coach's suitability for the role.
Muller and several other Bayern players have, in theory, been afforded an escape during the international break, but the 29-year-old revealed it is not so simple.
