Manor Solomon's stoppage-time winner secured Leeds United the Championship title as they won 2-1 at Plymouth Argyle, whose relegation was confirmed.

With Burnley beating Millwall 3-1, Leeds take the title on goal difference having secured promotion back to the Premier League last month, after two seasons away.

Argyle took the lead when the impressive Mustapha Bundu's shot came back off the post and went in off Sam Byram - just moments after the Plymouth forward had clipped the Leeds upright.

Leeds, who topped the table going into the final day, were repeatedly frustrated by a dogged Plymouth side until early in the second half when Willy Gnonto fired in Solomon's cross.

The visitors had a Joel Piroe goal ruled out for offside with 17 minutes to go as Daniel Farke's side hunted the winner they knew was required to secure the title.

But just as it seemed they would have to settle for second place, Solomon cut in from the left and fired low into the bottom corner to send the travelling Leeds fans wild and set up a trophy lift celebration after the final whistle.

Leeds started well as Joe Rodon and Brenden Aaronson saw efforts saved by Conor Hazard before they fell behind.

Bundu had given Leeds a warning a minute before the goal as he beat three men before blasting an effort that grazed the outside of the post.

When the resurgent Sierra Leone forward cut in from the left moments later, the net did bulge as his low effort came back off the far post and bounced in off a helpless Byram.

Piroe almost equalised within a couple of minutes when he turned Jayden Bogle's shot over the bar from six yards as Leeds tried to restore parity quickly.

Byram, Ao Tanaka and Willy Gnonto all had half-chances, but Leeds failed to create another really good opening before the interval.

Piroe again fired over as the second half started like the first ended before Gnonto equalised from close range after Solomon had crossed low from the byline.

Byram saw a glancing header go wide of the post midway through the second half while a Piroe effort was disallowed when Gnonto was adjudged to be offside as he received the ball before crossing it for his team-mate - a call which replays suggested was very marginal.

As news of Burnley going ahead filtered through, Farke brought on Patrick Bamford and Largie Ramazani to try and get a title-winning goal.

But it was Plymouth who almost snatched a winner when Ryan Hardie curled an 88th-minute effort wide from inside the box, while Callum Wright sent a tame low shot into the arms of Karl Darlow two minutes later as the hosts caught Leeds on the break.

However, just as it seemed all hope of the title had gone, Solomon broke into the penalty area and fired low past Hazard - sending the packed away end into raptures.

Plymouth Argyle head coach Miron Muslic told BBC Sport:

"I am proud, very proud.

"We faced today by far the best team in our competition, the champions. We were relegated since last week and still showed this kind of performance to make it very difficult for Leeds to break us - it shows the good spirit and character of the lads.

"Our obligation today was to give it all, we played for Plymouth Argyle, we played for the Green Army and we wanted to reward our fans for the last time with a strong performance.

"The lads went all in and we simply needed maybe just 120 seconds to have a result we deserved. But that's when you face the champions. They're ruthless, that's why Leeds are where they are.

"Congratulations for an outstanding season to Leeds, deserved champions and congratulations to my colleague Daniel Farke."

Leeds United head coach Daniel Farke told BBC Sport:

"It feels pretty good. I want to send my congratulations to Burnley, to Scott (Parker), I think they have done a fantastic job.

"Of course I'm happy that we won this game in the final stages and are officially allowed to label ourselves as champions and be the best team this season.

"It's an emotionally moving day because we have invested so much and wanted to crown ourselves with some silverware.

"It feels pretty, pretty special in the dressing room and I'm very happy for my players and staff, it means so much for them, and also our ers."

Leeds United winger Manor Solomon speaking to BBC Radio Leeds:

"I can't put into words what I'm feeling right now. It is a dream come true to score the winning goal and take this championship. Throughout the season we've shown we deserve this trophy and to finish in the first spot. I'm so glad it happened.

"We all knew what was happening at Burnley and we knew we needed to score. It will take me a few days to digest what happened today, right now I'm going to celebrate.

"I want to celebrate with my partner, with the club's employees. We deserve it. I've been focused on this season; in two or three days we will talk and see what is happening. I don't know what the future holds [Solomon is loan from Tottenham] but I can just say I love [Leeds]."
