due to the new rising corona infection numbers, the dfb decided at the beginning of the week to continue the second half of the season at the beginning of january without spectators and thus with ghost matches in the bundesliga 
That was somehow to be foreseen and also to be expected that this would come again. Some teams had already played without fans for the past 2 weeks.
Lets see maybe the situation will get a bit better at the start of the second half of the season , but i guess it will be not.
As long as they dont decide that nobody plays all is good.
