As other have suggested, success on the pitch and the value of the club are 'inextricably linked' (remember that phrase?!). Similarly, if the supporters -in essence the customers- are not happy, they are not putting money into the club, and therefore the club doesn't have such a great value. Therefore if Markus simply saw us as a way of making money - which I would neither be surprised or particularly disappointed with- I would not be too worried, as it is vital that the team keep performing and the supporters keep coming to the game and spending money on the club for its value to rise. I'm not sure whether the bit about legal action is a hint at something, but if it is that would certainly be slightly worrying as it would perhaps suggest there is something being hidden from us. However, as long as the team on the pitch continues to progress, I'm more than happy to know Markus is probably looking to make a profit eventually, as we would undoubtedly be left in a better position when he left than when he bought us.
I do think it is good that we are asking these kind of questions though, providing we keep it 'hypothetical' and do not cause unnecessary rifts between fans and the club. I'd much rather we made enquiries and were cautious in our enjoyment of Markus' money than end up deep in the sh!t like the rabble down the road.
