Watch: Andrea Bocelli sings as Leicester City lift Premier League trophy after amazing 5000/1 title triumph on May 7, 2016

It was the shock to end all shocks over a Premier League season as Leicester went from relegation battlers to champions of England in just a year.

It was a perfect storm for Claudio Ranieri's 5000/1 outsiders, who found the usual big guns struggling with only Tottenham really able to mount a serious challenge.

Some cruelly say that Spurs managed to finish third in a two-horse race that season as Arsenal eventually pipped them to second, when it looked for some time that Mauricio Pochettino was going to lead them to glory.

It was the Foxes who found the right formula though, with a counter-attacking style that teams could justnot figure out. Their stingy defence kept things tight, their hard-working midfield battled before unleashing Jamie Vardy and Riyad Mahrez going forward.

Shorter odds than Leicester winning the league pre-season (5000/1)

• 500/1 – Simon Cowell to become Prime Minister
• 500/1 – Discovery of the Loch Ness Monster
• 1000/1 – Sir Alex Ferguson wins Strictly Come Dancing
• 2000/1 – Kim Kardashian to become president of the USA
• 2000/1 – Elvis Presley is found to be alive
• 2500/1 – Then-Arsenal boss Arsene Wenger sacked & replaced with Piers Morgan

As the months rolled along we all still though Leicester would fade, but they kept going and May 7 2016 will forever be etched in their history as they lifted the trophy on an emotional day at the King Power Stadium.

A 3-1 win over Everton was the icing on the cake, but the key games came throughout the season. Here we look at five key wins...

September 13, 2015: Leicester 3 Aston Villa 2

A defining moment in both clubs' seasons which sent them in different directions. Goals from Jack Grealish and Carles Gil had put Villa 2-0 up but Ritchie De Laet started the comeback with 19 minutes left, then Jamie Vardy levelled with the second goal in his record-breaking 11 game scoring run. Nathan Dyer's last-minute header won it for the Foxes.

January 13, 2016: Tottenham 0 Leicester 1

The second of three games between the sides in 10 days saw Leicester win the crucial Premier League match as Spurs took the FA Cup honours. Robert Huth's 83rd-minute header decided it and ended a streak of three goalless games for the Foxes. It moved them seven points clear of Tottenham, who sat fourth, with Ranieri's side then joint top with Arsenal.

February 6: Manchester City 1 Leicester 3

In the middle of a three-game spell against Liverpool, City and Arsenal the Foxes stunned their hosts at the Etihad. Huth's early goal put City on the back foot before Riyad Mahrez left Martin Demichelis in another postcode to drive in an early second-half goal. Huth's second rendered Sergio Aguero's late consolation meaningless.

April 24: Leicester 4 Swansea 0

All eyes were on how the Foxes could cope without the suspended Vardy after he was banned following a red card in their previous 2-2 draw with West Ham. Ranieri's side emphatically answered any critics as they brushed aside the Swans, with Vardy's replacement Leonardo Ulloa scoring twice. Mahrez and Marc Albrighton started and finished the rout and 24 hours later Tottenham drew 1-1 with West Brom to leave Leicester three points from the title.

May 1: Manchester United 1 Leicester 1

After Tottenham failed to beat West Brom, Leicester were presented with their first chance to clinch the title if they could win at Old Trafford. Again without Vardy, given an additional one-game suspension following his dismissal against the Hammers, they were behind early on after Anthony Martial scored for United but captain Wes Morgan levelled and when Spurs failed to win at Chelsea the following day, Leicester were crowned champions, amid wild celebrations in Jamie Vardy's house.

May 7: The trophy is lifted

Leicester finally got their hands on the trophy following a 3-1 victory over Everton on the final day of the season, which typically featured a brace from Jamie Vardy either side of a strike from the club's longest-serving player Andy King. The most surreal and unexpected of parties had already begun with a spine-tingling pre-match performance from Italian tenor Andrea Bocelli, who belted out renditions of Nessun Dorma and Con Te Partiro while standing alongside Claudio Ranieri.
