The 22-year-old departs Palace after three successful years in South London, making 60 appearances and scoring four goals.
Devenny joined Palace in August 2023 from Scottish Championship side Airdrieonians and, having impressed for – and eventually captained – our Under-21s side, made his full Premier League debut at Selhurst Park against Fulham in November 2024.
This duly earned Devenny his maiden international call-up for Northern Ireland. A fortnight later, the midfielder memorably scored his first Premier League goal away at Aston Villa.
He also scored in Palace’s successful FA Cup run in 2024/25, finding the net in our fourth-round win over Doncaster, and converted the winning penalty in our 2025 FA Community Shield triumph over Liverpool.
Devenny also featured six times – scoring once – in Palace’s trophy-winning UEFA Conference League campaign.
Chairman Steve Parish said: “We are all hugely proud of Justin’s development at Crystal Palace, particularly his role during the most successful period in the club’s history.
“He is a fine young gentleman, and he leaves with the best wishes of everybody here for the future.”
