on the BBC web site they have a preview of the games, and produce lots of stats. Until recently, the Everton ones were really negative, now they are (mostly) very positive:-
BIG-MATCH FACTS
EVERTON have climbed to 15th - their highest position in the table since August with four wins and a draw from their last six outings. If they're able to follow-up Sunday's one-all draw at Manchester United with maximum points against West Ham they would rise another two rungs, to within two points of their opponents.
David Moyes' side have lost only one of the last seven Premiership contests. They may be the only club still in single figures in the "Goals For" column of the top table, but they've still gone 35 League encounters since a goalless draw.
Everton and West Ham have met each other 100 times in League combat with the Merseysiders ahead by 50 wins to 30, with 20 draws. The Toffees are unbeaten in home Premier League meetings with the Eastenders since 1994, winning seven and drawing two.
