The West Yorkshire club were guaranteed automatic promotion from the Sky Bet Championship after second-placed West Brom lost 2-1 at Huddersfield.
Leeds had moved on to 87 points on Thursday following their 1-0 home win against Barnsley and West Brom’s defeat left them five points behind with one game to play.
Jubilant fans gathered at Elland Road to celebrate the club’s return to the top table of English football, while the players were also in party mode as they danced and saluted supporters from the windows of the stadium.
And videos on social media showed manager Marcelo Bielsa, the inspiration behind the club’s resurgence, elbow-bumping fans near his home in Wetherby as they congratulated him.
However, the owner of a BMW car spotted at Elland Road will not be celebrating this morning as it was badly damaged.
Homegrown midfielder Kalvin Phillips declared Bielsa the “best manager in the world”.
The 24-year-old told BBC Radio Leeds: “There’s no manager I would rather be under than Marcelo Bielsa right now.
“At an age when I’m trying to develop, he’s the perfect manager to have. The Premier League is the best league in the world and, after 16 years, we’re back in there.”
Captain Liam Cooper said the club’s promotion had “still not properly sunk in”.
“Our club, our fans and our players have sacrificed so much – we’ve been in the doldrums for 16 years,” he added.
“To be part of this team and to lead this team to promotion back to where we know we’ve always belonged is unbelievable.”
It has been a long and often tortuous road back for Leeds, who were relegated from the Premier League in 2004 amid a spectacular financial meltdown.
The West Yorkshire club have spent 13 seasons in the Championship and three in League One after dropping into the third tier for the first time in their history in 2007.
Leeds’ debts had spiralled to over £100million in 2003 under former chairman Peter Ridsdale and there were fears the club could go out of business.
They were forced to sell all their players and other assets, including Elland Road Stadium and their Thorp Arch academy, and have since stumbled from crisis to crisis under a succession of different owners.
Leeds went into administration in 2007 under Ken Bates and fared little better under subsequent owners GFH Capital before the arrival of controversial Italian Massimo Cellino.
During Cellino’s chaotic three-year ownership Leeds had seven different managers, but current owner Andrea Radrizzani bought a 50 per cent stake in Leeds in January 2017 to signal the dawning of a new era.
