-Chelsea are unbeaten in 21 Premier League home games against Everton since November 1994 (W11, D10).
-It represents Everton's longest run of away games without a win against another club in the Premier League. Only against Leeds (36) have they had a longer away run without a win in league history.

Chelsea:
-Chelsea have won four consecutive league games, scoring 11 goals without reply. They last won five in a row in a single season in December 2013-January 2014.

Everton:
-They ended a five-match winless run in all competitions by beating West Ham last weekend.
-Everton's 2-0 victory represented their first clean sheet in six league matches. However, only Spurs have conceded fewer goals this season.
