Norway great Brede Hangeland slammed Manchester United's performance for defeat to Crystal Palace.
Commentating for TV2, Hangeland blasted Harry Maguire's role for Palace's opener scored by Jordan Ayew.
"Disastrous defending. The world's most expensive defender makes a mistake I can't understand.
"It's an unforgivable junior error," said Hangeland.
However, Hangeland says Anthony Martial deserved an early penalty.
He also stated: "It was so wrong that it was completely hopeless."
