Definitely yes!!!
Markus may have only been with us a year but he may well just be the most important figure in Saints history. With the possible exception of MLT. I remember his wife saying that he listened to our game against Bournemouth in the LC, went to sleep with a big smile on his face and never woke up. The other thing I've heard is the first thing he did when he purchased us was go around local business', found out how our administration had affected them and made them all a donation to reimburse them which he didn't have to do, in secret as well as he didn't like being "praised".
I'll add my contributions to the "open letter" thread later. The man will be a Saints legend forever.
