Manchester United have hired performance psychologist Rainier Koers to observe their training sessions.
Dutchman Koers was among the staff present for their training camp in Cadiz earlier this month after he was recommended by manager Erik ten Hag. Club sources say Koers, of the Talent Academy, comes into training "a couple of days a week".
Koers describes himself as a life coach who "guides people who get stuck in their lives due to major events".
