The Football Association of Ireland has announced that Eileen Gleeson will depart her role as assistant manager with the Republic of Ireland in order to take over as manager of Glasgow City.
The Dubliner had been in the role since October 2019, when Vera Pauw started her reign as Ireland manager.
She will continue to work with the squad for the upcoming World Cup qualifying double-header against Sweden and Finland, while also overseeing a home-based training session with SSE Airtricity Women's National League players.
Gleeson will then officially take up her new role with Glasgow City in November, replacing interim head coach Grant Scott.
Irish internationals Aoife Colvill, Niamh Farrelly, Clare Shine and Claire Walsh all play for Glasgow, who have won every Scottish Premier League title since 2007 and reached the quarter-finals of last year's Champions League.
The UEFA Pro Licence holder previously led Peamount United to league glory in 2011 as well as winning two League Cups in 2012 and 2013, while she also guided UCD Waves to a League runners-up spot and an FAI Women's Cup Final.
She said: "This is a bittersweet feeling for me because on one side I am delighted to have been given the opportunity to work with Glasgow City - one of the most progressive clubs in women's football - but on the other side I am leaving on the cusp of very exciting times for women’s football in Ireland and the beginning of the World Cup Qualifying campaign with the Irish team.
"But I feel that this opportunity with Glasgow is one that I couldn't turn down in order to take the next step forward in my career and development as a manager. It is really unfortunate that it comes just when we are starting our World Cup qualifying campaign - something that I was really looking forward to as I genuinely believe that we can qualify for the tournament in 2022.
"The last two years have been unbelievable. I've learnt so much by working alongside Vera. The same with the players and the backroom staff, it was a pleasure to work with all and to share so many highlights. I firmly believe that this team is capable of doing something special. I wish everyone involved the very best of luck going forward and will always be the team’s number one supporter. "
Pauw said: "I am really disappointed to lose Eileen from our team, having built up such a good working relationship and achieved a lot in the development of our squad over the last two years.
"But I'm also really happy for her to take this step in her career by accepting the role with Glasgow City. I wish her all the success she can get both in the Scottish Championship and in the UEFA Women’s Champions League. She has so much to offer and will add all her experience and knowledge to the team.
"Wherever I have worked I have always wanted an assistant coach from the country I worked who knew the local players and had a strong understanding of the football culture of the country. In that regard, Eileen has been one of the best that I've worked with in my career and I thank her for all that she brought to the role with the Ireland squad.
"We have enjoyed some intense and great times together, along with the players and the extended backroom staff, and I'm sure the work that Eileen has done will help us in our quest to qualify for the 2023 FIFA Women's World Cup."
