Donny van de Beek praised Harry Maguire's reaction to being booed during Manchester United's pre-season friendly victory against Crystal Palace.
Maguire's name was jeered when the teams were read out before kick-off and his first few touches of the ball were also met by audible boos from a 76,000-strong crowd.
The United captain has been criticised following his poor performances last season, but Erik ten Hag has backed him to remain as skipper and hinted he will partner Lisandro Martinez in defence this season.
