At No7 in terms of win rate alone is the legendary Sir Matt Busby, who managed victories in 51.4 per cent of his games. Many consider him their greatest boss ever, having led the club to European Cup glory in 1968 after surving the 1958 MunichAir Disaster.
At No6 is Louis van Gaal with a 52.4 per cent win rate. The Dutchman was in charge from 2014 to 2016, winning the FA Cup final against Crystal Palace in his final game.
David Moyes may have only lasted ten months but he is at No5 in the list, with a win rate of 52.9 per cent. The Chosen One was given the near impossible job of replacing Sir Alex Ferguson - something no one has seemed to have managed so far.
At No4 is 1999 legend Ole Gunnar Solskjaer, who won 54.2 per cent of his games after being parachuted into replace Jose Mourinho in 2018. Managed two top four finishes but was given the boot in 2021. Will always be a legend though.
At No3 is the man Ole replaced, The Special One himself. Had a win rate of 58.3 per cent, including victories in the 2016/17 Carabao Cup and Europa League finals. Called his second place finish with the Reds in 2017-18 one of his greatests achievements.
Despite being arguably the greatest manager of all-time, Sir Alex Ferguson only manages second place, with a win rate of 59.7 per cent. Had a poor start to Old Trafford career, explaining why figure is not higher, but made up for it with 13 league titles afterwards.
At No1, despite seemingly being under pressure since he took over in 2022, is Erik ten Hag. Has a win rate of 60 per cent up to the Man City derby, which was his 100th game. Despite topping the list, he still needs to convince the new owners he is the man to lead them next season.
