While at Liverpool Hope, Hayes coached the women's football team from 1997 to 1999. In 1999, she moved back to London, helping develop youth players at
Croydon and
Crystal Palace. She was appointed as the head coach for the
Iona Gaels women's team, of
Iona College in
New Rochelle, New York, on 22 January 2003, where she remained until the end of the 2005 season. She returned to England to become the assistant first team coach for
Arsenal Ladies over 3 seasons between 2005 and 2008, during which time the team won 11 major trophies including three Women's Premier League titles, three FA Women's Cups and the
UEFA Women's Cup. At the same time, she was also the club's Academy director, overseeing the development of young players. After she was sacked in 2010, she took up a technical director role at
Western New York Flash and advised them on transfers, helping to create a team that won the 2011 Women's Professional Soccer championship. After another stint as a consultant for
Washington Freedom, Hayes returned to London and worked for the family business, Covent Garden FX, a currency exchange.
Chelsea During the mid-season
2012 Summer Olympics break on 14 August 2012,
Chelsea hired Hayes as manager for the remainder of the
2012 season following the resignation of
Matt Beard to become manager at
Liverpool. Hayes managed her first match with Chelsea on 18 August 2012 in a 1–0 win at
Doncaster Rovers Belles.
Marija Banusic,
Gemma Davison and
Niamh Fahey also joined Chelsea, signing from
Kristianstads,
Liverpool Ladies and
Arsenal Ladies respectively. Later on in the season, Hayes won the race for Reading and England forward
Fran Kirby for a British record fee. With the agonising memories of final-day defeat still fresh in memory, Hayes guided her side to a historic league and cup double, edging the FA Cup Final thanks to a lone strike from
Ji So-yun late on in the first half. Later on in the season, they avenged themselves by winning The FA WSL 1 title, after hammering
Sunderland at home 4–0 to secure the trophy. In the
Women's Champions League, Hayes's side reached the last 16 after defeating
Glasgow City. After their 2–1 home defeat by
VfL Wolfsburg, Hayes criticised
The Football Association for poor fixture scheduling, insisting that the competition is "geared to French, German and Swedish teams, and until we change that or listen to clubs like Chelsea we are always going to get knocked out in the early rounds."
2016–17 season Hayes' side finished second in The FA WSL 1, five points adrift of Champions
Manchester City. Chelsea however won the
FA WSL Spring Series, an interim edition of the FA WSL. Hayes led the side to first place, finishing on the same points as Manchester City but beating them on goal difference.
2017–18 season Aided with the addition of new players including
Ramona Bachmann,
Maren Mjelde,
Erin Cuthbert and
Crystal Dunn, Emma Hayes guided her side to finish top, in a reorganised FA WSL1, on goal difference. The team also played the FA Cup competitions and reached the semi-final but were knocked out by Birmingham City in a penalty shoot-out.
2019–20 and 2020–21 seasons Hayes sought to rebuild the team at the conclusion of the 2017–18 season around new recruits
Sam Kerr,
Pernille Harder,
Melanie Leupolz,
Magda Eriksson, and
Ann Katrin Berger, having moved on some key first-team players. The 2019–20 and 2020–21 season saw her team win back-to-back WSL titles in what were record breaking years, following a trophy-less 2018–19 campaign. Given Chelsea's dominance in the 2020–21 season in both Europe and England, some observers hailed them as one of the best teams ever. Hayes became the first woman manager to reach the Champions League final in 12 years. On 16 May, her Chelsea team, also playing their first-ever Champions League final, lost 4–0 to
Barcelona Femeni. Hayes won the 2020–21 FA WSL
Manager of the Season award. Two months later, she signed a new long-term contract with Chelsea. In the same year, Hayes was inducted into the FA WSL Hall of Fame. Based on the 2020–21 season, on 17 January 2022, she was adjudged
The Best FIFA Football Coach, beating off competition from
Lluís Cortés and
Sarina Wiegman.
2023–24 season On 4 November 2023, Chelsea officially announced Hayes would depart after the ongoing season to “pursue a new opportunity outside of the WSL and club football.” Reports in the United States indicated that Hayes was in advanced talks to become the new manager of the
United States women's national team. On 14 November 2023, Hayes was named Head Coach of the
United States women's national team starting at the conclusion of the
WSL season. On 21 January 2024, Hayes became the first woman to win the Football Writers Association Tribute Award in its 42 year history. Chelsea lost to Arsenal 1–0 after extra time at the
FA Women's League Cup final. After the match, Hayes was seen to have shoved Arsenal head coach
Jonas Eidevall as they shook hands. Hayes claimed it was due to Eidevall's "unacceptable male aggression" on the touchline after an altercation with
Erin Cuthbert during the match. Chelsea went on to crash out of the
Women's FA Cup and
UEFA Women's Champions League in the semi-final stages but ultimately won a fifth WSL title in a row to send Hayes out on a high.
United States In November 2023, Hayes was named head coach of the
United States women's national team (USWNT) starting at the conclusion of the WSL season. On 1 June, in the team's debut under Hayes and the first of four
friendlies before the Olympics, the United States won 4–0 against
South Korea. Despite the short time she had with the team, she took them through an undefeated Olympics run, winning the gold medal game 1–0 against
Brazil on 10 August. The team went 6–0 and scored its opponents 12–2 at the tournament. On 28 October, she was awarded the inaugural
Women's Johan Cruyff Trophy as the best coach in the women's game. Before the next major tournament cycle, Hayes introduced the "WNT Way", a plan to develop the women's game in the United States through a unique "female lens". Hayes saw her first loss with the USWNT on 26 February 2025, dropping 2–1 to
Japan at the
2025 SheBelieves Cup. She has broadened the USWNT player pool during her tenure, giving 17 players their USWNT debuts in her first 20 games, the most by a new manager since the early days of the program. ==Personal life==
