Yes, but surely he'd also appreciate that he knows a lot of details about the club that most if those making the comments don't ( for example progress with transfer targets ).
It depends.
If they have definate top quality signings on the way soon, I can't imagine they are that worried, as the mood will turn around very quickly.
If not, they probably know themselves it will be a grim season, and that fan mood will drop through the floor anyway.
