Katharina Lienherr is not going to stay at the club forever.
The question is in what way, under what requirements and at what specification will the club be sold? Is it simply a case of she'll listen to any offers that come in? is it a case of we're actively going out to source buyers? Is there a big scam going on currently to get KL some cash to make up the difference she feels she can earn (unlikely to me). None of that is really clear.
As I've said many times before, there aren't tons of good, trustworthy, seriously loaded investors/owners out there waiting to sink £100m into a football club.
