SIR ALEX FERGUSON famously claimed his biggest challenge as Manchester United manager was “knocking Liverpool off their f****** perch”.When the great Scot left Old Trafford after clinching one last Premier League title in 2013, it was mission f****** accomplished.Legendary Man Utd manager Sir Alex Ferguson took pride in ‘knocking Liverpool off their perch’Credit: PAHowever, the Red Devils are now far from the threatening club they once wereCredit: GettyBut what Fergie achieved during the course of a glorious 27-year reign, new Kop manager Arne Slot is threatening to undo in his debut season.The crown United won 12 years ago was their 20th, putting them two clear of Liverpool at the top of the list of English champions.Jurgen Klopp brought the Merseysiders back to within one of United by clinching the crown in 2019-20.So if Slot can convert his team’s current lead at the top of the table into a trophy lift in May, he will put them level with their North-West rivals.Read More in FootballAnd given Liverpool’s superior European Cup and Champions League record — with six wins to United’s three — the Anfield faithful would once more have the numbers to back their claim to be England’s greatest club.The one crumb of comfort for United fans in recent years is the other lot down the M62 have failed to take advantage of United’s decline in the same way Fergie filled his boots during Liverpool’s barren years.Many Reds supporters would argue their team fell off that perch rather than being pushed by United.Poor recruitment and a failure to exploit the commercial opportunities of the Premier League breakaway cost the Kop dear as much as United’s quality under Fergie.Most read in FootballFOOTBALL FREE BETS AND SIGN UP DEALSArne Slot has carried Liverpool to the top of the Prem table in his first seasonCredit: AlamyIn between Kenny Dalglish’s third and final league title as Liverpool boss in 1990 and Klopp’s victory 30 years later, Ferguson and United were champions 13 times.After Klopp announced his decision to leave Anfield last January — and his second bid for a Quadruple fell even flatter than the first — United supporters probably breathed a sigh of relief.Manchester United vs Newcastle: Player Ratings RevealedThey have seen just how hard it is to replace an iconic manager and to compete with those other noisy neighbours, Manchester City.But Slot has come in to Anfield — and, rather than picking up where Klopp left off, has coaxed new levels from a group of players who looked spent when finishing third in last season’s three-way title race.So the United faithful will travel to Anfield for Sunday’s game fearing not only another hiding on the day but also a more long-lasting kick in the guts at the end of the season.The Red Devils’ recent Premier League record against Liverpool is humiliating, with just one win in the last eight meetings and six goals scored compared to the Reds’ 26.Losing to your fiercest rivals is bad enough, but the manner of the defeats has often been shocking.In the 2021-22 season, Klopp’s Reds won 5-0 at Old Trafford and then 4-0 at home. But United’s real nadir came at Anfield on March 5, 2023 when Liverpool scored seven without reply.So the United faithful will travel to Anfield for Sunday’s game fearing not only another hiding on the day but also a more long-lasting kick in the guts at the end of the season.It was not only the biggest margin of victory in a rivalry dating back to 1894, it also equalled the worst defeat of United’s entire history.Yet most Liverpool supporters would swap a one-off thrashing like that for another championship.And despite their team’s apparent superiority right now, there will be a small voice of caution in the back of the mind of all but the most optimistic fans.Because failing to beat United damaged title bids led by Klopp more than once.United have suffered some embarrassing defeats against Liverpool in recent yearsCredit: AFPIn February 2019, Ole Gunnar Solskjaer’s side held Liverpool to a 0-0 draw at Anfield. The Reds finished one agonising point behind City at the end of the season.And Erik ten Hag’s United drew both league games against Klopp’s side last season.Had Liverpool beaten United at Old Trafford on April 7, they would have been level on points with City and two ahead of Arsenal with six games to go.But after Mo Salah’s late penalty salvaged a 2-2 draw, Liverpool lost at home to Crystal Palace the following weekend and watched another title chance slip away.Losing to your fiercest rivals is bad enough, but the manner of the defeats has often been shocking.There is further encouragement for United fans that their team can still lift themselves when playing Liverpool and form can go out the window in this fiercely-contested derby.Bruno Fernandes grabbed the winner in a 3-2 FA Cup fourth round victory in January 2021.And most memorably last March, United came from behind twice to beat Liverpool 4-3 in the sixth round and went on to lift the trophy.The hero of that Old Trafford victory was Amad Diallo, with a dramatic winner in stoppage-time at the end of extra-time. Or, to put it another way, in Fergie time.READ MORE SUN STORIESHow the United fans would love another shock win for new boss Ruben Amorim’s side on Sunday.And recapture hope their club can remain alone on the title-winning perch where Ferguson left them.Sir Jim Ratcliffe’s first year at Man UtdSIR JIM RATCLIFFE’S minority takeover at Manchester United was announced on Christmas Eve in 2023 – and a lot has happened at Old Trafford since…December 2023 – Man Utd confirm Ratcliffe’s takeover on Christmas Eve, vowing to invest £245m into Old TraffordJanuary 2024 – Ratcliffe and right-hand man Sir Dave Brailsford photographed meeting Erik ten Hag during tour of Carrington January 2024 – Omar Berrada poached from Man City as new CEO February 2024 – Ratcliffe’s £1billion, 27.7 per cent takeover officially completed February 2024 – Former CEO Richard Arnold quits board as Ineos pair John Rees and Rob Nevin addedMarch 2024 – Ratcliffe bans words “awesome” and “lukewarm cappuccino” in bizarre moveMarch 2024 – Matt Johnson appointed head of women’s footballMarch 2024 – Ratcliffe announces plans to build “Wembley of the North” to replace Old TraffordMarch 2024 – Man Utd NYSE share price drops to $13.73 on March 21 – down from $20.52 immediately after Ratcliffe takeover in DecemberApril 2024 – Senior staff club credit cards and private cars cancelled April 2024 – John Murtough quits as football director April 2024 – Jason Wilcox appointed technical director after compensation package agreed with Southampton May 2024 – Ratcliffe turns Carrington “toxic” after sending email to employees slamming “disgraceful” lack of cleanlinessMay 2024 – Work finally starts on leaking Old Trafford roofMay 2024 – Man Utd finish eighth in Premier League, worst-ever finish May 2024 – Ratcliffe gives employees just one week to decide if they want to accept redundancy May 2024 – Staff forced to pay for own transport to FA Cup final and only given one ticketMay 2024 – Pre-match party and hotel for senior staff before FA Cup final axedMay 2024 – Man Utd shock rivals Man City to win FA Cup despite suggestions Erik ten Hag will be sacked regardless of resultJune 2024 – Man Utd announce £50m plans to upgrade Carrington training ground June 2024 – Ratcliffe introduces strict “back to work” policy forcing staff to come into officeJune 2024 – Ratcliffe scores own goal with comments about women’s teamJuly 2024 – Man Utd finally agree deal to bring in Dan Ashworth as sporting director after four months of gardening leave at Newcastle, who received £3m in compensationJuly 2024 – Erik ten Hag signs shock new contract extension until 2026July 2024 – Ruud van Nistelrooy and Rene Hake appointed assistant managers, Andreas Georgson first-team coach and Jelle ten Rouwelaar goalkeeper coach.
