Chelsea are leaking chances away from home
Expected goals (xG) measures the quality of chances. Over their last 5 home games Everton created 1.6 and allowed 1.4 a game. Over their last 5 away games Chelsea created 1.1 and allowed 1.9.
The model would have called Everton win, 2–1, with a 39% chance (bookmakers 30%). Here is everything that went into it.
Expected goals (xG) measures the quality of chances. Over their last 5 home games Everton created 1.6 and allowed 1.4 a game. Over their last 5 away games Chelsea created 1.1 and allowed 1.9.
Last five league games: Everton took 7 points, Chelsea took 7.
Chelsea have 15 goals from 10.3 xG this season. Finishing like that tends to cool off, so we lean on the chances, not the goals.
2 of the last 4 meetings were drawn or won by one goal. Past meetings count for little in the model.
If Chelsea's defence were only average, this would swing to an away win (42%).
Everton 2–1 Chelsea, home win, too close to call
