#3 Frank O'Farrell
Frank O'Farrell had the impossible job of replacing Sir Matt Busby, taking over the reins at Manchester United in the summer of 1971.
Trending
The Red Devils were one of the most dominant clubs in European football at the time, winning the European Cup three years before Farrell's arrival. There were huge expectations on O'Farrell as he became the first and only Irishman to be appointed Manchester United manager.
In his debut season in charge, O'Farrell led United to first spot in the First Division for a brief period. That was the first time the Red Devils secured the top spot in three years. However, O'Farrell soon fell out with some of the biggest names in United's dressing room, including the likes of George Best.
The Irishman was provided £500,000 to rebuild the squad, which was an extremely high amount at the time. However, O'Farrell failed to achieve the desired results, and was sacked after a 5-0 loss to Crystal Palace.
In 56 matches as Manchester United manager, O'Farrell registered 21 wins, 14 draws and 21 losses for a dismal win percentage of 37.0.
#2 Louis Van Gaal
After securing a third-place finish for Netherlands at the 2014 FIFA World Cup, Louis van Gaal took over as manager of Manchester United.
The Dutchman signed the likes of Angel Di Maria, Luke Shaw, Radamel Falcao and Ander Herrera in his first season in charge. He spent over £165 million in his first transfer window. With some world-class talents in his ranks, Van Gaal enjoyed the board's full backing. However, he was extremely underwhelming in his two-year spell at Manchester United.
Van Gaal won only one trophy at Old Trafford - the 2015-16 FA Cup title. However, he was sacked just two days later, failing to mount a substantial challenge for the Premier League title.
The Dutchman did not endear himself to the Manchester United faithful with his bland playing style, and the club failed to achieve the desired results.
In his debut Premier League season in charge of United, Van Gaal's side were in ninth place with 13 points and three victories after ten games. That was Manchester United's worst start to a season since 1986-87 under Ron Atkinson.
In 103 matches as Manchester United boss, Van Gaal secured 54 wins, 24 draws and 25 losses.
#1 David Moyes
David Moyes is the first among a host of managers who have struggled at Manchester United following Sir Alex Ferguson's departure.
Dubbed 'The Chosen One', Moyes took over the reins at Old Trafford in the summer of 2013. He was personally named by Sir Alex Ferguson as his long-term replacement following an impressive 11-year spell with Everton. At the time, Moyes was regarded as one of the most talented managers in the continent. But he never hit the ground running at Manchester United.
The Scotsman could never fill the big shoes of Sir Alex Ferguson, and looked out of depth during his nine-month spell at Old Trafford. Moyes did not really receive the backing of the Manchester United board, making only two signings in his first transfer window in charge.
In 51 matches as Manchester United manager, David Moyes had a record of 26 wins, ten draws and 15 losses. He had a dismal win record of just over 50%, and was replaced by Ryan Giggs, who took over as the interim manager.
