Manchester - Former Manchester United star Gary Neville and fans on Tuesday blasted the team's owners for the way manager David Moyes was sacked.
Neville said that Moyes should have been given more time before his ousting.
The Manchester United Supporters Trust said the manner of the sacking was a "PR shambles" because of media leaks about the sacking.
United's American owners, the Glazer family, ousted Moyes after less than 10 months in the post, with the team slumping in the Premier League and Europe's Champions League.
"The last 15, 16 hours or however long it's been, I don't like it, it's not the way in which the club should portray itself," Neville, who won eight Premier League titles with United, told Sky Sports.
"But it's the modern world, it's how things seem to be dealt with now, but I'm a traditionalist and I think it could have been dealt with a whole lot better.
"I believe in managers being given time, I think they should be allowed to complete their work."
But Neville added that Manchester's results this year have been "poor".
"As a fan I've not enjoyed watching it -- I'm sure David Moyes himself hasn't enjoyed watching it."
Neville said Manchester United players must "take massive responsibility" for the bad season.
"I never once during my 17/18-year career at United turned around after a game and thought 'you lost us that game boss'.
"It's always the players. Players have to take responsibility, accountability in football."
Sean Bones, vice chairman of the Manchester United Supporters Trust, expressed outrage at the way British newspapers knew about the impending sacking on Monday, calling it a "PR shambles" for the club.
"The story leaked before David Moyes has been spoken to, and that's not the Manchester United way. There was no dignity or class in the way they went about it."
Former United and England striker Michael Owen said the club may have had no choice but to act now.
"With the summer looming and a huge transfer kitty available, United had to be 100% (certain) Moyes was the right man," Owen said on his Twitter account.
"Evidently they didn't have the confidence in him in which case makes the timing absolutely right. Now the big question is who's next?" he added.
Dwight Yorke who played in United's team which won the Champions League, Premiership and FA Cup, believes interim manager Ryan Giggs could be the person to take permanent charge.
"There is never going to be someone like Sir Alex Ferguson but what we're given here is a young manager who is looking to break in," said Yorke.
"He's not got the managerial skills but we thought that David Moyes had those skills going into Manchester United with the experience that he had for 11 years being at Everton and the wonderful job that he'd done.
"But he hasn't been able to turn things over at Manchester United.
"I think for togetherness and getting the results and playing a certain way, a brand of football that is more eye-catching, the Man United way, I feel that Ryan Giggs is the right person."
