Ecstatic fans rushed into the streets of Leicester on Monday as the outsiders won the Premier League in a triumph seen as the most astonishing in the history of English football.

Dancing crowds dressed in the team's blue jerseys hugged each other and chanted songs honoring heroes such as manager Claudio Ranieri and striker Jamie Vardy, linchpins of Leicester City's first title triumph in its 132-year history.

Borussia Dortmund's Germany star Mats Hummels is facing the wrath of his team's angry fans, bitter that their club's captain has admitted he wants to play for rivals Bayern Munich.

Despite helping Dortmund to a 5-1 rout of Wolfsburg, Hummels was booed and whistled by a section of home fans in their 81,359 sell-out stadium each time he touched the ball on Saturday.

A year ago as Gareth Bale sneaked out the side exit to Real Madrid's Santiago Bernabeu stadium he was engulfed by cat calls and insults by his own fans.

They were infuriated at his inability to take a slew of chances as Madrid bowed out of the Champions League semi-finals to Juventus.

Leicester City manager Claudio Ranieri hailed his players' "determination" and "spirit" after their improbable Premier League title triumph was confirmed on Monday.

"I'm so proud," Ranieri said, in comments published on the Leicester website. "I'm happy for my players, for the chairman, for the staff at Leicester City, all our fans and the Leicester community."

Leicester City completed their fairytale Premier League title quest on Monday after Tottenham Hotspur could only manage a 2-2 draw in a pulsating game with outgoing champions Chelsea.

With Leicester's players gathered at the home of striker Jamie Vardy to watch the match on television, Spurs went 2-0 up, only for goals from Gary Cahill and substitute Eden Hazard to bring Chelsea level and complete one of the most astonishing stories in professional sport.

Two goals from Gonzalo Higuain gave Napoli a 2-1 win over Atalanta keeping them on track for second place in Seria A on Monday.

And third-placed Roma stayed in the race for the automatic Champions League berth with a 3-2 away win at Genoa.

In the rough-cut figure of Jamie Vardy, newly crowned Premier League champions Leicester City possess the living embodiment of the rags-to-riches tale that has captivated fans around the world.

Six years ago, Vardy was playing amateur football for Stocksbridge Park Steels in England's seventh tier and working part-time at a factory making medical splints.

Off the tourist trail and loved by few but its residents, Leicester was a sleepy place until a king who died over 500 years ago and footballing triumph roused it from its torpor.

Some people even believe that the discovery of the skeleton of Richard III and Leicester City's astonishing Premier League win are linked.

Leicester City forward Jamie Vardy has been voted the 2016 Footballer of the Year by the Football Writers' Association (FWA), it was announced Monday.

The 29-year-old striker took the award as a clear winner ahead of team-mates Riyad Mahrez, who had already taken the Player of the Year award voted on by his fellow professionals, and N'Golo Kante.

Morocco captain Mehdi Benatia has threatened to leave Bayern Munich if they sign fellow center-back Mats Hummels from rivals Borussia Dortmund for next season.

Hummels, 27, has told Dortmund he wants to leave with a year left on his contract and Bayern have confirmed they are negotiating to bring the Germany star to Munich.
