Manchester United boss Erik ten Hag forced his humiliated players to listen to Liverpool celebrate their 7-0 win on Sunday.
The Red Devils were beaten by the remarkable scoreline at Anfield in the Premier League.
Instead of having the players talk among themselves or assess the result immediately after the final whistle, ten Hag had his players quietly listen to the Liverpool celebrations.
Per The Mirror, he wanted them to reflect on those scenes, ensuring they never repeat such a capitulation again.
United's players were back at their Carrington training ground on Monday.
The Red Devils take on Real Betis in the Europa League on Thursday.
