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 Alex Aldridge, of newsatden.co.uk, selects Millwall's five best No9s… and one to forget!

5. Jimmy Constantine (1948-52)
Constantine's career began during the second world war when, while serving in the Grenadier Guards, he was handed a professional contract by Rochdale. He joined Millwall in 1948, having scored two hat-tricks against the club - one for Manchester City and one for Bury. Referred to as Connie by Millwall fans, Constantine finished as the club's top scorer in three of his four seasons in south London.

4. Jack Cock (1927-30)
Cock was an astonishingly prolific striker during the first quarter of the 20th century, as well as being a decorated first world war soldier, an actor and a singer. He even made two appearances for the England national team, scoring in both matches. Cock joined Millwall in 1927, towards the end of his career, and scored an incredible 77 goals in just 115 appearances. He was renowned for being quick, two-footed, and while only 5ft 11in tall, an accomplished header of the ball.

3. Derek Possee (1967-73)
Millwall paid what was then a club record fee of £25,000 to sign Possee from Tottenham in 1967. Small and nippy, with a deft first touch, Possee formed a formidable partnership with Keith Weller. He got himself on the scoresheet consistently during his five-and-a-half years at the club, bagging a total of 79 goals for the Lions in 223 appearances before signing for Crystal Palace.

2. Teddy Sheringham (1984-91)
Sheringham, who came through Millwall's youth ranks before signing as a professional in 1984, lies second in the club's all-time leading scorer list, having held top spot from 1991 to 2009. He scored 111 goals in 244 appearances in all competitions for the Lions before joining Nottingham Forest for £2m in 1991. In the 1987-88 season, Sheringham scored 15 goals during Millwall's first year in the top division.

1. Neil Harris (1998-2004 & 2007-11)
Bomber, as Harris is affectionately known by Millwall fans, is the club's all-time leading scorer and will forever be a icon in the club's history books. Signed for just £30,000 from Cambridge City, Harris scored 93 goals during his first spell with the Lions. During that time, he successfully battled testicular cancer and his resilience on and off the pitch made him a huge fans' favourite. He returned to the Den in 2007 after a short time away from south London and when he finally left for good to join Southend in 2011, he had scored a total of 138 goals for the club.

And the worst…
Carlos Fangueiro (2005-06)
With a name more befitting an exotic ballroom dancer than a Championship footballer, Millwall fans were excited by the arrival of versatile Portuguese star Carlos Fangueiro in August 2005. He was handed the No9 shirt by then manager Colin Lee. He made 13 appearances during an injury-plagued season, scoring only once, before joining Walsall on a free transfer the following summer. To make matters worse, the Lions were relegated that year. The definition of a flop!
