EMMA HAYES revealed today she felt “unwell” at the end of her time as Chelsea boss due to the stress of the job.

Hayes, who ended her 12-year reign in charge of the Blues to become head coach of the United States women’s team, is back in London as her new side prepare for Saturday’s friendly with England at Wembley.

The 48-year-old, who guided Chelsea to a fifth successive Women’s Super League title in May, opened up about the toll the job took on her health before she made the switch to international management.
