O’Sullivan is reportedly joining Gotham on a 12-month loan from Liverpool FC, with the possibility of a permanent move included in the agreement. Her switch comes after spending the opening part of 2026 in the Women’s Super League, making this another significant turn in an already eventful year.
Before the move, O’Sullivan explained why Gotham appealed to her.
“I’m incredibly excited to join Gotham FC and return to the NWSL,” she said. “This club has established itself as one of the top teams in the world with an incredible culture and ambition to compete for every trophy.”
That ambition now has a proven midfielder at its disposal. O’Sullivan’s game has long been built around composure, competitiveness and the ability to dictate rhythm in the centre of the pitch - qualities that can become especially valuable during a long campaign.
The reported comeback victory immediately places O’Sullivan inside a team with momentum. Gotham’s challenge will be managing expectations at the top while integrating a player arriving midway through the season.
For O’Sullivan, the move offers more than a fresh start. It is a chance to play a prominent role in a side targeting major honours, while also returning to a league in which she has reportedly won championships and Shields.
The occasion carried an extra layer of significance with Roy Keane reportedly watching from the stands. O’Sullivan has long regarded the former Manchester United and Republic of Ireland captain as a childhood idol.
“Thank you so much Roy Keane for taking the time to come down to see the game. Absolute legend!” O’Sullivan wrote.
The next NWSL fixtures will show whether her debut was the beginning of a sustained push for the summit - and whether Gotham’s reported loan agreement could eventually become permanent.
