Ole Gunnar Solskjaer was so incensed with his Manchester United
players after the Cardiff defeat that he threatened to sell half the squad, according to reports.
United were left humiliated after a 2-0 defeat by Neil Warnock's side at Old Trafford.
According to The Sun
, Solskjaer told his players that he planned to sell some of them as he plots a summer rebuild of his team.
The United boss also cancelled the club's end of season debrief on Monday after calling his players a 'disgrace'.
The 46-year-old has been left angry at the attitude of some of his players after a terrible end to the season.
United finished the season in 6th place in the Premier League to qualify for the Europa League.
Solskjaer knows he needs to act quick in order to prepare properly for next season.
Plans for next season may also need to be altered should Watford find a way to beat Manchester City in the FA Cup final on Saturday.
Should Watford win the FA Cup, United would have to start the Europa League in the second round of qualifying.
Asked what Solskjaer thought was behind United poor end to the season, he said: 'We just need to get that consistency at home, being able to win games and dominating more games. I think we've been fantastic with counter-attacking football but must improve on dominating more games.
'The last period has been difficult but that doesn't mean the team or players have become any worse. We've just found it hard. It's been a long, emotional season for them physically, as well as emotionally.
'When you lose your manager halfway through the season, it's not easy for the players.'
