I would play nothing but a mix of reserves and youth players next game and tell the first team players they had better hope they don't win. Then I would put a few of the women's team very visibly on the bench as unofficial "substitutes". If they win, I would go with those players for the rest of the season and leave all the first teamers to rot in the reserves. If they lose badly, resign, hold a press conference explaining what is actually happening behind the scenes, retire, and maybe write another novel or something. He's got nothing to lose now.
