Tbf the Bernardo thing is a bit tongue in cheek but until he's holding up another shirt (or at least publicly declare his desire to leave a la Kane), I'll take any info that he wants out with a pinch of salt.
City said we wouldn't sell Agüero at any price... and lo and behold we didn't until we didn't need him anymore.
That is how you make a definitive statement. Of course every player will eventually leave but it's absolute dishonesty to say you will keep a player (4 times) and then sell them a year (or less) later.
Levy is a master of pulling wool over the eyes of the fans. Tottenham, with the wealth of their owners, should be competing for major honours every year. They aren't.
