Manchester United manager Erik ten Hag told Alejandro Garnacho that he was withdrawn against Crystal Palace - having less than half-an-hour earlier come on as a substitute - for the good of the team.
The Argentine, 18, was taken off with just three minutes of normal time left on the clock and replaced by Harry Maguire, just 28 minutes after stepping off the bench himself. Garnacho had come on in the 59th minute to replace Wout Weghorst.
United were 1-0 up at the time and doubled their advantage just three minutes later, courtesy of Marcus Rashford's 19th goal of the season. However, Casemiro's 70th-minute red card changed the landscape of the contest, offering Palace hope of getting back into the match, which they did six minutes later through Jeffrey Schlupp's clever finish.
