THIS weekend’s Manchester derby (Man City Vs Man United) is at risk after the Met Office issued a warning, saying eight inches of snow is forecast in sub-zero temperatures on Sunday.

They have also upgraded their warning from 'yellow' to 'amber' as snow is set to fall between 4am and 6pm across Greater Manchester, which will be combined with sub-zero temperatures.

With Manchester United & Manchester City set to kick-off at 4.30pm, by game-time the snow may have well and truly settled, with temperatures set to drop to -1 degrees.

And while the Old Trafford pitch does have undersoil heating, should the precipitation be too heavy – or the stands be too icy to be deemed safe – the game could well be postponed.

The snow is set to cover all of Greater Manchester and even Liverpool

There are also health and safety issues outside of the ground that could prevent the game from going ahead, with fans unable to get in the ground.

United will hold talks with local authorities should the weather become an issue and there is a precedent for postponing Premier League games.

Their match away at Chelsea was called off in 2010 over health and safety concerns. So too was Arsenal's clash with Bolton the same season.

'Make sure you take close note of local emergency services,' a Met Office spokesperson said. 'If you do have to travel, make extra time for journeys. It could cause disruption to transport services.

'Take extra care as there is the chance of ice being around as well.'

The weather will spread to Liverpool, which means there could also be a risk to the Merseyside derby between Liverpool and Everton as well.
