-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 earned a 3-3 draw in the corresponding fixture last season courtesy of John Terry's controversial 98th-minute equaliser - the latest goal recorded in the Premier League in 2015-16.
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.

-Diego Costa has scored three goals in his three league games against Everton. However, he was sent off in the FA Cup quarter-final defeat at Goodison Park last season.
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.

-Yannick Bolasie has set up four league goals for Romelu Lukaku this season, the most by any player for a specific team-mate.
-Lukaku failed to score in his 15 appearances in all competitions for Chelsea between 2011-2013.
