Chairman Mick Wallace called the westerners "grossly unprofessional"
Shane Keegan's appointment as Galway United's new manager has not gone down well in Wexford.
Keegan left Wexford Youths after the side were relegated to the First Division following their play-off defeat to Drogheda United on Friday night. He was appointed Galway's manager on Sunday, signing a two-year contract.
The 34-year-old spent five seasons in Wexford, which culminated in the team's first promotion to the Premier Division ahead of the 2016 season. Working with primarily an amateur team, Keegan guided the team to an 11th place finish.
News of Keegan's potential move to the west, broke hours before Wexford's 3-0 loss to Drogheda, and the timing has not gone down well with Wexford Youths Chairman Mick Wallace. On Sunday night, the TD revealed the club will go to the FAI seeking compensation from Galway United.
"On Friday morning, the day of the biggest game in WYFC history, one that would determine whether the club could retain its place in the Premier Division of LOI, or not, the word spread that a rival League of Ireland club was about to announce the appointment of Shane Keegan as their manager."
"For this news to spread on such a day, let alone the fact that Keegan was under contract to Wexford Youths FC for another year, was grossly unprofessional on the part of Galway United and a blatant breach of League of Ireland rules. WYFC shall be lodging a formal complaint with the FAI and seeking adequate compensation."
"While deeply unhappy with the manner of Shane's departure, the club will continue to hold him in high regard, and wish him well."
Galway United finished in ninth place last season, with Keegan replacing Tommy Dunne, who was sacked in September.
