POMO

It was reported today that Norwich City has painted the away team dressing in deep pink in an attempt to reduce the players testosterone levels during the match preparation, an idea introduced by Dr Alexander Latinjak, a psychologist from the University of Suffolk (not Norfolk note??). Such tactics and attention to detail are inspired by other sports, most commonly from the devious American Football clubs!
So far this season, Norwich have lost to WBA in the league 3-4 and beaten Stevenage in the League Cup. Effective? It is all about "marginal gains" apparently.
Such attempts to gain any advantage over your opponents is not recent. John Beck was famous for creating havoc with the away dressing room at his clubs; Cambridge United.....

Louis van Gaal's Manchester United complained that their dressing room was too hot when they visited Wolfsburg in the Champions League, a game they lost 2-3.

At the Stadium of Light, Sunderland painted the opposition's changing room a blue with yellow tinge which apparently induced sickness and colds and at Benfica there were huge posters of aggressive home fans pasted on the walls.

At the Emirates, a large cupboard central in the away dressing room obscured the players' heads should they be sitting on the team benches by their lockers. Mind you the rest of it looks pretty good...

The Crazy Gang, AFC Wimbledon, never stopped improvising and turning the heating down in winter and interfering with the hot water was one favourite, along with loud music from the boom box!

At Anfield the away dressing floor was dangerously slippery, whilst other dressing rooms have been known to be L-shaped to prevent universal eye contact with the coach.

At Stamford bridge the coat hooks were ridiculously high up making players stretch and put pressure on their ankles....can you believe this? whilst the helpful "tactics board" was on the back of the main door in which had a notice stating that the door must be kept open in case of fire.
Bizarre chairs in the Russian Anzhi Makhachala away dressing room greeted Spurs in the Europa League tie-Spurs won 2-0.
Don't get me on Beck's slightly flat warm up balls generously provided by the home team for the oppo and the long grass in the corners of the pitch to slow down the "long ball", a valuable tactic of some  of our POMO clubs (position of maximum opportunity).

I might add, the opposition, North Gawber, coming out of the away dressing room at Far Lane, Hepworth, last Saturday, complained that their dressing room was too hot....they won't be complaining in December! They won 4-0?!!
