One of the greatest No. 10s ever to wear the Manchester United shirt was Dennis Viollet, one of Sir Matt Busby's "Babes". There are very few players who have worn the shirt since the War. In this article we mention them all.
Anyone who was at, or even watched, the second leg against Real Madrid will have seen the unveiling of the Busby Babes memorial flag shown in the picture above.
While most people remember, or have heard of, Sir Bobby Charlton and Duncan Edwards, Dennis Viollet was up there as one of United's best ever goalscorers.
He was one of the first "Busby Babes" and had come through what we would now call the Academy and made his debut in 1953.
Like Charlton, he survived the Munich Air Crash and was also pivotal in holding the side together afterwards. He scored a record 32 goals in 36 games in the 1959/60 season; and went on to notch a total of 159 in 293 games before being sold to Stoke City.
Someone for whom there is even less information is Stan Pearson. He was an "inside-forward", one of two players who played a little behind the "centre-forward" and inside the wingers. They linked play from back to front, so to score many goals here was more impressive than a striker.
Stan managed 148 goals in 343 appearances, putting him in 12th place in the all-time list, only two behind Ruud van Nistelrooy.
In the days before substitutions and modern tactical systems, beginning with 4-4-2, there were 11 players, numbered by their position on the field. So No. 10 was given to whoever played "inside-left."
Because of this some of our ten selected players may surprise you. They are presented in a hierarchy where those who wore the shirt regularly rank above those for whom it was not their "famous" number.
So before you read on, see how many of these No. 10s you can name?
