The now 35-year-old spent just three months as interim manager of boyhood club Cardiff City and was unable to save them from relegation to League One in 2024-25.
Ramsey will face off against his former club after being confirmed as the new head coach of freshly relegated side Oxford United, his first permanent managerial role.
Speaking to the club’s website, he said: “It’s an honour and privilege to be appointed Head Coach of Oxford United.
“From my discussions with the Club, I can sense the ambition and desire for success, which gives me great excitement about this opportunity.”
“This is a moment I have been preparing for over many years,” Ramsey added.
“I’ve played under some of the best managers in the game and experienced high-pressure environments throughout my career.
"I want to use what I’ve learnt to bring a culture of high standards, professionalism and work ethic to this talented group of players.”
