It’s not just the effect on the person wearing the suit. Psychologically, one views another wearing a suit as being organised, successful, ambitious, intelligent. This can transfer in a sporting sense as a team being tactically intelligent, well drilled and hungry for success. If it gives a team a slight psychological advantage then why not use it? Would the same criticism be said if they walked out onto the pitch on game day wearing different clothes over their strips instead of the same track suit tops?
People on this forum complain that we don’t act like a big club because we don’t buy the big players and show ambition, yet when we finally get the right people in place and start to do things a bit more professionally and try to gain advantage, no matter how marginally small it may be, we still find a way to take a pot shot at the club.
