This is the second derby today in Premier League. Again two teams which represent England in Champions League.

Both team loves to win this season, Arsenal did not lost at home this season, they have only a lost away at Middlesbrough, while Chelsea have two losts, both away, with Aston Villa and Manchester United.

A big difference looking at statistics is the number of goals(average/game). Arsenal have a average of 3.25 goals/game at home (2.94 on all games). Chelsea have a average of 2 goals/game away (2.06 on all games). Chelsea from 7 games away in 7 of them there was a under 2.5 goals and just 1 Over. From all games there are 13 Under and 3 Over, but I think this is not a mistery.

The biggest difference between them was 4 goals and was in season 1930-1931 when the score for Chelsea vs Arsenal was 1-5. An Arsenal victory, but away.
