Sonia Bompastor has been appointed as Chelsea Women's new head coach, replacing Emma Hayes at Stamford Bridge.
Hayes oversaw a fifth straight Women's Super League title for the Blues this season but departed to take up a role with the United States Women's national side.
Bompastor was expected to come in as the replacement for Hayes, with the announcement confirmed on Wednesday as Chelsea managed to strike a compensation deal with Lyon Women.
The 43-year-old, who has signed a four-year deal with Chelsea, leaves the French side after a successful three years in charge, winning three league tiles and the Women's Champions League in 2022.
"The sporting directors and I conducted a thorough and considered recruitment process to identify Emma’s successor," Chelsea's general manager Paul Green said of the appointment.
"Sonia's vision, coaching philosophy and winning mentality made her the outstanding candidate.
"She is a world-class coach with a proven track record of success on the biggest stages that will instantly command respect from the dressing room."
Bompastor won seven trophies during her time with French heavyweights Lyon but lost the Champions League final last Saturday against Barcelona.
She was capped 156 times by the French national team before retiring in 2013, and subsequently becoming the first woman to win the Champions League as a player and coach after her success with Lyon.
Assistants Camille Abily and Theo Rivrin will join Bompastor as Chelsea prepare for a new era without Hayes, who departs the Blues after a 12-year spell that yielded 14 major domestic titles.
