There must have been hopeless, hapless players in Manchester United's darker days. Between 1922 and the Second World War, the club bounced between the old First and Second Divisions, nearly going bankrupt in the process.
Sir Matt Busby created the most successful period in the club's history up till 1969, but after he retired, United once again drifted, to the point where it was infamously almost sold to a daydreamer called Michael Knighton.
During this period it is inevitable that there were some poor players who because of that have slipped from supporters' memories.
Whenever the question is asked "who were United's worst players?" attention is likely to fall on the last 30 years or so. Furthermore, details are scant before that period.
So how do you gauge who was worst? Commonly people focus on the worst signings— especially in an age of astronomical transfer fees. Others would look at technical skills and playing records. Finally, attitude and application are relevant.
In a way it is even harder to narrow down the worst than the best, or most popular. For example, Juan Sebastian Veron and Diego Forlan are often cited, because they failed to live up to the hype and potential. Kleberson would be on many people's lists for similar reasons, but when you look at how many times they have played at the highest level of International football, they can't be that bad.
So we've put together an eclectic selection from the last 40 years. They are not in any particular order. Once again, it is a matter of opinion, so please put forward other suggestions if you don't agree.
