Ramsay will be an assistant coach for the Welsh national team, while also performing his duties of first-team coach for the club concurrently.
Wales manager Rob Page has hailed the 31-year-old as ‘one of the best young coaches in football’, saying: “This change gives us an opportunity to build on our success, by drip feeding new players into the squad at the right times.
“Hopefully in twelve months we’ll then have taken the next batch of players to represent Wales at a top level.”
Ramsay, who works closely with United manager Erik ten Hag, is ‘excited’ at the opportunity to put his expertise to the test on an international level.
