Squad number: 7
Profile: Henderson enjoyed an excellent first season for Millwall, having been signed as replacement for Steve Morison in the summer of 2011.
He scored on his debut in the 2-2 draw away to Reading on the opening day and went on to bag a total of 19 goals, 15 of those coming in the league, without which the Lions would have struggled to stay in the Championship.
Henderson scored three hat-tricks for Millwall in the 2011-12 campaign, two in the league and one in the FA Cup. His brute force, work rate and goal ratio soon saw him become a fan favorite at The Den.
He began his career at Doncaster's academy before being picked up by Reading, where he produced a goal ratio of one in every seven games. He then moved to Gillingham for a nominal fee, but missed his entire debut season through injury.
In 2005, Henderson joined Aidy Boothroyd’s Watford for £450,000 and was an integral part of the side which eventually gained promotion to the Premier League, scoring the third and final goal against Leeds in the Championship play-off final in 2006.
In 2008, he joined Sheffield United for £2 million, but his three years at Brammal Lane were marred by injury and suspension.
Did you know: Before Henderson, the last person to score three hat-tricks in one season for Millwall was Teddy Sheringham, who hit four in the 1990-91 campaign.
