London: Chelsea manager Carlo Ancelotti believes his team's push towards the defence of their Premier League title has been powered by the sun.
"I don't want to joke, but when the sun comes out and the temperature is hotter, for us it's better. We suffer in the winter temperatures," said Ancelotti after Saturday's 2-1 win over Tottenham at Stamford Bridge.
"It could be a good reason to explain this. Last year, this moment was very good for us. Good home form."
