The England international played for Leeds for an initial eight year spell after signing as a 12-year-old in 2001.
In a Q&A with the Aston Villa website, Lions captain Fabian Delph was asked whether he supported any other football teams, and reminded Leeds United fans that he used to, and still may hold a soft spot for the club.
"I grew up supporting Leeds United and obviously went on to play for them," he said, before going on to talk about playing football as a child in Bradford.
"I always used to be out playing on the estate I lived on.
"There were loads of kids that used to run around playing on the streets - bottles for goal posts and scruffy footballs but great memories."
Delph played for Leeds for one full season as a youngster, having come through the academy that he joined in 2001, though he made at least one appearance in each of the two seasons before that.
Making his debut in May 2007, the midfielder was captain of the reserve side, and by 2008 had cemented a spot in the Whites' midfield under Gary McAllister and his successor Simon Grayson.
The Bradford-born player featured 50 times in the 2008-09 season, scoring six times and being selected in the League One team of the year.
Delph moved to Villa that summer for £6 million, as reported by the Guardian, having fought off interest from Tottenham and Manchester City.
At just 19-years-old, the midfielder struggled to get appearances in the Premier League, something that wasn't helped by serious knee and ankle injuries.
It was only after a return loan spell at Elland Road in 2012 that Delph managed to impact the Villa first team, and in the last three seasons he has gone from strength to strength, winning his first England cap and seizing the captain's armband for the Villans.
