Why are there blue lines on the Emirates Stadium pitch during Arsenal vs Manchester City?

Groundstaff had to paint the lines blue for Thursday evening's big Premier League clash after temperatures plummeted.

There was something a bit different about the pitch at the Emirates Stadium during Thursday night's Premier League meeting between Arsenal and Manchester City .

The inclement weather across London and the rest of the UK over the last few days caused by 'Storm Emma' had led to concerns that the match would be called off, and the Arsenal groundstaff took precautions over that by painting the lines on the pitch blue.

Groundstaff painted the lines of the pitch in case more snow does fall before kick-off, with forecasters suggesting as such.

The blue lines will then be more visible than the white ones should the pitch get icy

Lines were also painted the untraditional blue colour during for Wednesday night's FA Cup fifth round replay between Tottenham and Rochdale at Wembley.

However, groundstaff there were forced into a last minute u-turn as officials said that the VAR wouldn't work with the blue lines as it had been programmed to only recognise white ones.
