Squad number: 20
Profile: Dublin-born striker Keogh joined Millwall on the final day of the transfer window in January 2012 for a fee of around £500,000.
Known for his high work rate, skill on the ball and ability in the air, Keogh scored 10 goals in his first 18 appearances to help the Lions maintain their Championship status.
Keogh began his senior career at Leeds United but failed to make a league appearance under then-manager Kevin Blackwell. He was subsequently loaned out to Scunthorpe and Bury before being signed by Scunthorpe permanently for £50,000 in 2005.
He went on to become a real success with United, scoring 19 goals in 86 appearances to propel them towards promotion from League One.
After impressing then Wolves manager Mick McCarthy, he made the move to the Black Country for around £850,000 in 2007. Whilst at Molineux, Keogh scored 19 goals in 118 appearances and spent time on loan at Cardiff, Bristol City and Leeds.
In that time he scored five goals in 47 appearances, including a last-minute winner for Cardiff against Millwall in September 2010.
Did you know: Keogh has several tattoos on his right forearm – including an image of his daughter, St. Christopher, a Guardian Angel and a poem.
