There is more chance of scientists finding alien life form this year than Newport County beating Manchester City in the FA Cup this Saturday, according to bookies Sportnation.bet.

The Welsh side are a massive 28/1 long shot to beat Pep Guardiola's stars and progress to the Quarter Finals of the FA Cup, longer than the 25/1 quoted for an extra-terrestrial discovery.

Indeed, other major bookmakers such as William Hill and BetVictor go as long as 40/1 against the League Two side, so confident are they in ruthless City’s FA Cup quest.

In other comparative sportsbook odds, Jose Mourinho is deemed more likely for a third spell at Stamford Bridge this calendar year (16/1) while it’s also more feasible Declan Rice captains England in the same timeframe at 20/1.

In what looks set to be a pivotal year politically, the bookies also rate it more viable that President Trump wins a Nobel Peace Prize (16/1) or Boris Johnson quits the Tory party at 20/1 than a win for The Exiles.

Other outrageous but more realistic bets than a home win at Rodney Parade include McDonalds causing a storm and introducing a new vegan burger at 6/1, Tiger Woods winning two or more majors at 25/1 and England lifting both the Cricket World Cup and Rugby World Cup in 2019 at 20/1.

Saturday evening's clash brings together the favourites for the cup City (5/4) and the biggest underdogs at 750/1, in one of the biggest mismatches in recent history of the competition.

A spokesman for Sportnation.bet said: “Our number crunchers make it more likely we discover life from outer space this year than Newport topple City’s Galacticos as the competition’s biggest underdog prepare to face the hot favourites.

“The list of events we think have a better chance of taking place this year across the world of news and sport tell the full story and should County upset the odds, anything is possible.”
