Erik ten Hag will face Rayo Vallecano in his first home game in charge of Manchester United.
United start their pre-season campaign with a clash against Liverpool in Thailand on July 12, before heading to Australia for friendlies with Melbourne Victory, Crystal Palace and Aston Villa.
The Red Devils will then head to Oslo as Ten Hag faces Diego Simeone’s Atletico Madrid on July 30.
United return to Manchester to cap off their pre-season schedule with a friendly against LaLiga side Vallecano at Old Trafford.
That will be Ten Hag’s first game at the Theatre of Dreams and United’s football director John Murtough hopes the fans will give him a warm welcome.
“Pre-season is all about preparation and this is a great opportunity for those squad members who may not have featured in some of our earlier tour and pre-season matches to get valuable minutes on the pitch – and where better to do this than Old Trafford?,” he said, as quoted by United’s official website.
“This will be the new manager’s first match at Old Trafford, and I am sure the fans will provide him with a warm welcome.”
