With more trophies than any other club in the history of English football, Manchester United is arguably one of the biggest clubs in the world. Their current record of 20 league wins and 21 Community Shields is unparalleled in England. They are one of only five clubs to have won all three UEFA club competitions.Notably, the club has fallen on tougher times since the exit of long-time manager Sir Alex Ferguson. And in recent years their trophy-laden cabinet has missed the touch of an English Premier League title.Successive managers Louis van Gaal and Jose Mourinho have guided the club to an FA Cup, a Community Shield win, a Europa League win, and a League Cup win.However, the English Premier League title remains elusive. There have been calls for the sacking of current United manager Ole Gunnar Solskjaer coming to the fore after recent games this season. It seems as though domestic glory might yet elude United again.In better years long gone, Manchester United were a domestic force to be reckoned with. Famous records were broken by world-class stars, many of whom would easily take a spot on this list.Players like Dennis Viollet and George Best might have scored well over 150 goals each in their respective careers at Old Trafford, but even their achievements have been bested. Even Cristiano Ronaldo's 122 goals aren't enough to give him the left-wing forward slot on this list.Without further ado, let's take a look at some of Manchester United's highest-scoring players of all time in their respective positions.Manchester United: All time scoring XI by positionsGoalkeeper: Alex Stepney - 2 goalsAlex StepneyA record-breaker in his own right, Alex Stepney is one of the very few goalkeepers to have scored a goal. Scoring two penalties for United in 1974, Stepney notably scored more goals than any other keeper in the club's history.His most legendary moment in Manchester United's history, however, came when he saved an almost certain goal from Benfica. This save took the 1968 European final into extra time. The Red Devils eventually pulled through and won their first European title.Manchester United@ManUtdLegendary #MUFC keeper Alex Stepney recalls moving to OT, 50 years to the day since signing: bddy.me/2bE0Fav10:48 AM · Sep 1, 2016856366Legendary #MUFC keeper Alex Stepney recalls moving to OT, 50 years to the day since signing: bddy.me/2bE0Fav https://t.co/k6vBIzSGOFA reliable man between the sticks, Stepney led the charge from the back for over 10 seasons, making 175 clean sheets in 539 appearances for the club.
