The 18-year-old joins City’s Next Gen squad ahead of the 2026/27 PGA Under-21 season.
An exciting and technical midfielder, Brennan moves to Manchester with a wealth of experience in her native Republic of Ireland.
Indeed, Aoibhe broke into the Bohemians senior side in 2024 and went on to make over 50 appearances in the following two seasons.
She also earned recognition at international level, captaining the Republic of Ireland’s Under-19s as well as earning a senior call-up in April 2026.
The midfielder was set for her first senior cap in a pair of World Cup qualifiers against Poland, but injury prevented her from getting onto the pitch.
However, her quality on the ball, energy and experience mean she’ll likely feature in Carla Ward’s plans in the coming months and years.
