Hayes also discussed Chelsea perfect start under her successor Bompastor and said: "I'm so happy with their start to the season, so happy with Sonia's start with a group of players and people I know are tremendous. That to me, that's what it's all about.
"Because I'm happy with where I'm at and I know I couldn't have given any more, it's only right for the players to have a different direction. I'm the middle child of three, jealousy and envy don't enter my mind, I'm not that person.
"I know the changing room Sonia's got and I'm happy for her, that she gets to enjoy the fruits of many people's labour of a long period of time and put her own stamp on it.
"If Chelsea go onto bigger and better things… oh, that's my perfect story. All those players in the locker room know that about me. They have a growth mindset, Chelsea look fantastic this season and I'm delighted for them."
