This season Prostate Cancer UK is the official charity of The Football League. To celebrate, we've asked bloggers from each of the 72 clubs to count down their top five strikers to have worn the No9 shirt, in recognition of the fact that prostate cancer affects one in nine men.

Here blogger Ian Rands, from aunitedview.blogspot.com , selects Sheffield United's five best No9s… and one to forget!

5. Derek 'Doc' Pace (1957-64)
Pace was a striker with quick feet and physical strength that saw him score a fair number of headed goals, despite being less than 6ft tall. United's top scorer for six successive seasons, none of his 175 Blades goals came from the penalty spot and his first goal came just 68 minutes after signing for the club.

4. Bill Dearden (1970-76)
Dearden was converted from a right-winger by United manager John Harris. The step up in division and change of position invigorated Dearden, who used his pace and fearless nature to great effect. Benefitting from a quality supply line from Alan Woodward, Gil Reece and Tony Currie, his goals took United back to Division One in 1971.

3. Tony Agana (1988-91)
Agana was out of favour at Watford when his former manager Dave Bassett brought him to United. Partnered with Brian Deane, they proved perfect foils for each other and formed a deadly strike partnership. The pace and quick feet of Agana contributed 52 goals (and set up many more) and helped United to back-to-back promotions, taking them back to the top flight.

2. Mick Jones (1962-67)
A popular figure at United in the early 1960s. Scoring his first goals on his 18th birthday, Jones went on to score nearly a goal every two games. Comfortable with both feet as well as his head, he picked up two England caps while with United, before becoming the first in a line of Blades stars to move up the M1 to Elland Road, where he won two league titles and the FA Cup.   

1. Keith Edwards (1975-78 & 1981-86)
Edwards was twice a Golden Boot winner and his two spells at United generated 171 goals, averaging a goal every 1.7 games. Not tall, but quick and agile, his greatest asset was the ability to turn his man and get a shot away.  Contributing little to team play and with a confidence bordering on arrogance, he had the knack of finding himself in the right place at the right time.

And the worst…
Paul Williams (1988-89)
This was a player who appeared uncomfortable to be on a football pitch. Part of a struggling team, he made six appearances in an injury-hit 18 months at United.  At 6ft 3in tall he ought to have been the perfect target man, except he was more like 5ft 8in when he jumped. His Nobel peace prize-winning mother, Betty, displayed greater movement in the name of peace!
