Manchester's Key 103 will be the official commentary partner of Manchester United for the next three years, broadcasting full commentary on all games.
Key 103 and Magic 1152 will also continue to broadcast full commentary of Manchester City games – the only stations in Manchester to provide commentary for both.
Key 103 will launch a brand new show, Total Football, on the weekends with pre-match build up, commentary and post match analysis with the commentary team, guests and the fans, as well as a whole host of online extras including podcasts and a live webchat on Fridays with Manchester United legend Mickey Thomas and former Manchester City and England player Andy Hinchcliffe.
Gary Stein, Key 103 Programme Director said: "We have worked with Manchester City for the past five years and are delighted to add Manchester United to our line-up.
"Working with both clubs gives us balance and the opportunity to connect with football fans from both sides of the fence, making our weekend line-up unmissable."
BBC Radio Manchester will continue to broadcast commentary on all Manchester City games.
