The 2015-16 campaign delivered a thrilling play-off run for Millwall as The Lions, under club legend Neil Harris in his first full season, secured a 4th-place finish in League One. Spearheading the charge was the prolific Lee Gregory, whose 27 goals across all competitions, including 18 in the league, proved decisive in a campaign built on the fierce strike partnership with Steve Morison and a new core of academy talent. It was an unforgettable year of grit and momentum that ended in a heartbreaking 3-1 defeat to Barnsley in the Wembley play-off final.
