Chelsea have won the Premier League title every time they have been top at Christmas.
Chelsea are currently six points ahead of their rivals and are set to be top of the league at Christmas. The Blues have won the title each of the four previous times they have been top of the league at Christmas.
They won the title in 2005, 2006, 2010 and 2015 and all four times they were top at Christmas.
If history is to be repeated then Chelsea could be lifting the title again in 2017.
