Obviously you have never heard of mind games before.
Mind games might be ok with other managers or teams but to use them on his Clubs own fans is another matter. I still cant get my head around a manager telling his own Clubs fans not to turn up and support the Club regardless of the competition, cant remember any other Liverpool manager ever doing it, not even the first game Liverpool played in Tokyo all those years ago against Flemengo which was at the time a money making friendly, fans till went and the Club, manager and players all appreciated it.
