Profile: Lewisham-born Marquis is a product of Millwall's academy. He was handed his first professional contract in 2009 after impressing at youth level and during a loan stint at Staines Town, where he scored six goals in six games.
Marquis made his professional debut for Millwall in a 2-0 loss away to Bristol Rovers in the 2009-10 season, coming on as a 48th-minute substitute.
He briefly broke into the first team at the back end of the 2010-11 season after scoring a 93rd-minute equaliser at home to Norwich. He then struck against Preston in a 4-0 drubbing of the Lilywhites and bagged a brace away to Scunthorpe.
His form and ability to spearhead Millwall's attack at an early age was rewarded with a three-year deal in 2011.
Did you know: Marquis works as a part-time model for Manchester United defender Rio Ferdinand's magazine.
