All-time results record (League, FA Cup and League Cup)
Everton have lost only one of their 11 fixtures at Goodison Park so far this season - a 2-1 defeat by Chelsea on Sunday, December 30, 2012.
Albion's 2-0 victory over David Moyes' side in September is one of only three losses for the Merseyside club this term.
Steve Clarke's outfit could convert their second double of the campaign in this game - after already overcoming QPR home and away.
The Baggies and the Toffees are the two highest-placed founding members of the Football League.
Albion overcame Everton 4-1 in the first-ever meeting of the two teams at Anfield on Saturday, December 1, 1888 - it was each side's 13th league game.
The Blues have conceded only 26 goals so far this season - with only Manchester City (19) and Chelsea (22) able to claim a better defensive record.

Everton team news
David Moyes could welcome back Darron Gibson to his starting line-up after a one-month layoff with a thigh injury. Seamus Coleman missed Saturday's FA Cup clash with a leg injury, while Kevin Mirallas, who returned from a hamstring problem at the weekend, is likely to miss out after lasting only 18 minutes of the Reebok Stadium fixture. Tony Hibbert is also unlikely to feature for the Toffees and has been sidelined by a calf injury since December 1.
Michael Oliver will referee Wednesday's game. He has overseen 24 matches this season, dishing out one red and 58 yellow cards in the process. The Northumberland official last refereed the Baggies in their 2-1 home victory over Chelsea in November.
Selected odds from Bet Butler:
Everton to win: 8/13
Albion to win: 11/2
Nikica Jelavic to score first: 5/1
Romelu Lukaku to score first: 8/1
