Manchester United's rival supporters have laughed off Erik ten Hag's appointment on social media, claiming the Dutchman will 'flop harder than any other manager' in Premier League history.
United officially confirmed the Dutchman as their new boss on Thursday, with the 52-year-old taking over from interim boss Ralf Rangnick at the end of the season.
And while the majority of United's fanbase appear to be delighted with the decision to appoint Ten Hag, fans of their Premier League rivals are not at all convinced he will restore the club to its former glory.
In fact, many fans are claiming that Ten Hag will follow in the footsteps of those before him and will be unable to 'save' the club from its fall from grace.
Following the news that Ten Hag will become the club's fifth permanent manager since Sir Alex Ferguson retired in 2013, fans flocked to social media to mock his appointment.
One Twitter user was left in hysterics as they claimed that Ten Hag would be 'worse' than Ole Gunnar Solskjaer, who was sacked as Manchester United boss last November and was later replaced by Ralf Rangnick on an interim basis.
Solskjaer failed to win any silverware in his three years as United boss – with Ten Hag already promising to end their five seasons without a trophy when he takes charge.
Ten Hag has made a name for himself in Holland, winning two league and cup doubles at Ajax, but his lack of experience in one of Europe's 'top five' leagues has left rival supporters to write off his chances of success already.
An over-zealous United fan posted a rather tongue-in-cheek response to Ten Hag being appointed, claiming he will be the 'greatest manager of all time. Better than Pep Klopp Mourinho and Tuchel'.
But while the tweet was sent in jest, one rival fan responded by asking: 'What has he achieved in Europe?'
Another predicted that Ten Hag wouldn't make it past 12 months in the role, insisting that United fans will be calling for him to be sacked when he doesn't deliver instant success.
They wrote: 'I'll bookmark this tweet because In 6-12 months, #TenHaagout will trend on this app and United fans will call for his head.'
Another fan agreed, simply suggesting that the Dutch coach won't be able to solve the club's issues currently plaguing the club. They said: 'Erik ten Hag won't save you btw'.
One Arsenal fan confidently claimed Ten Hag will be one of the biggest failures in the Premier League.
They said: 'Ten hag will flop more than any other manager in the PL! Mark this tweet'
The Dutchman's appointment has been expected for some time since Sportsmail revealed a month ago that he had been interviewed for the job having moved ahead of Paris Saint-Germain boss Mauricio Pochettino.
Ten Hag said: 'It is a great honour to be appointed manager of Manchester United and I am hugely excited by the challenge ahead.
'I know the history of this great club and the passion of the fans, and I am absolutely determined to develop a team capable of delivering the success they deserve.
'It will be difficult to leave Ajax after these incredible years, and I can assure our fans of my complete commitment and focus on bringing this season to a successful conclusion before I move to Manchester United.'
Football director John Murtough said: 'During the past four years at Ajax, Erik has proved himself to be one of the most exciting and successful coaches in Europe, renowned for his team’s attractive, attacking football and commitment to youth.
'In our conversations with Erik leading up to this appointment, we were deeply impressed with his long-term vision for returning Manchester United to the level we want to be competing at, and his drive and determination to achieve that.
'We wish Erik the best of luck as he focuses on achieving a successful end to the season at Ajax and look forward to welcoming him to Manchester United this summer.'
