Mannion has represented United 55 times since her arrival from Manchester City in the summer of 2021 and is a fully fledged Republic of Ireland international.
Aoife helped keep a clean sheet on her Reds debut, on the opening night of the 2021/22 WSL campaign, playing the full 90 minutes in a 2-0 win over Reading at Leigh Sports Village. She would then unfortunately suffer a season-ending knee injury midway through the campaign, which would cut short her first term at United.
Mannion battled back her way back, however, showing true spirit and resilience, and would make her return to action for the Reds as a second-half substitute in United's FA Cup fifth-round win over Durham in February 2023.
