Well, the answer to #1 is a bit surprising, since he said publicly that he's not looking to move this year and intends to see out his contract, was just talking to Villa to show respect and get the experience.
Of course this is PR and you do have to lie by omission and such for the sake of the supporters, not driving up prices by announcing intent to buy, et cetera. If a manager is thinking of leaving, but may not, of course he's going to keep this private, it would only hurt the team to make it public.
Pretty cruel of the jerk who released the information, if Ole was only trying to protect the club.
