Manchester United have appointed Andy O'Boyle as the club's inaugural deputy football director.
O'Boyle, 39, has vacated his role as the head of elite performance at the Premier League to support United football director John Murtough, who was in the same role as O'Boyle when he joined the club in 2013.
Northern Irishman O'Boyle spent time coaching in the United academy and has rejoined the club after a 16-year absence.

O’Boyle said: “I am thrilled to be rejoining Manchester United at such an exciting time for the club, as the first team prepares for a fresh start under Erik ten Hag, and the academy and women’s teams go from strength to strength.
“Whilst it has been a privilege to serve the Premier League for the past five years, I can’t wait to get started at United and play my part in creating the right environment for football success.”
Murtough added: “We are delighted to welcome Andy back to Manchester United to take up this important role in the club’s leadership.
“Andy has experience across all technical areas of football, from fitness and sports science to scouting and recruitment.
“This will make him a valuable addition to my team at Carrington as we continue to strengthen leadership and strategic planning across all our football activities.”
Like Murtough, O'Boyle also went to university in Liverpool and also has a background in sports science, having been the head of science at Coventry.
O'Boyle was previously Jurgen Klopp's fitness coach at Liverpool and has also had stints with Wrexham and the England Under-21s.
