IF Leicester win the Premier League at Old Trafford on Sunday it will be the biggest betting shock in history.
Some bookies marked up the Foxes at 5000-1 at the start of the season and as we know dozens of people backed them at that prices – and many have cashed out.
To put in perspective Northern Ireland are 5000-1 to win the 2018 World Cup with Coral and Justin Bieber is 5000-1 to one day be President of the USA. To be fair to Bieber he'd do a better job than Donald Trump as long as he promised not to sing.
