There will have been little sorrow in the Arsenal and Manchester City camps when they heard the news that Chelsea manager Emma Hayes will depart at the end of the season for the United States.
Both of these clubs have spent the last four years trying and failing to end the Blues' domination of the Women's Super League.
Hayes' exit will bring uncertainty to a club that has been so stable for the last 11 years.
Arsenal and City should be rubbing their hands at that prospect, but they will also be desperate to ensure Hayes is not allowed to leave with yet more trophies to her name.
