Nope, but we can make judgements based on the evidence available. And the most likely scenario at the moment is that funding from the Liebherrs is slowly being pulled or has been pulled altogether.
There was a rumour when Markus passed away that he left a "trust fund" of sorts for the club, this would also tie into it. It's not a bad thing - it shows that clubs at this level CAN be self sustaining, although it only works for us because we have no huge mortgages to pay on stadiums, no shareholders to pay out to etc.
