It is one of the most famous moments in Premier League history and a classic example of psychological warfare in football
Mind games are so tightly woven into football nowadays that almost any pronouncement could be construed as forming part of a broad psychological offensive.
Jose Mourinho is considered a master of the trade, having regularly deployed curious techniques of unnerving rivals during the course of his career, while Jurgen Klopp recruited a dedicated psychologist to his backroom staff in order to help manage mental matters.
However, one of the standard bearers for the dark art of getting into the heads of opponents was Sir Alex Ferguson and his subtle needling of Kevin Keegan endures as an example of how effective it can be, as Keegan famously lost his cool then, ultimately, the Premier League title.
