Ten Hag operated in defence or midfield during his playing days and has welcomed the input of former South Africa international McCarthy, who scored goals across his career for the likes of Ajax, Celta Vigo, Porto and Blackburn Rovers.
When asked about the 45-year-old's influence since his arrival as the start of a special series of questions posed by fans, the manager explained the role given to the ex-striker, who is also credited with contributing to the sense of togetherness within the squad.
“In our coaching staff, we had a lot of defenders and midfield players," said Ten Hag.
