Arsenal are winless in five matches in all competitions for the first time since March 2016. The Gunners haven't gone six games without a win since October-December 1994.
Crystal Palace are now five points above the bottom three as Roy Hodgson continues to work his magic at Selhurst Park.
The Eagles have only lost one of their last 12 in the Premier League and that was against Arsenal in the reverse fixture.
Hodgson's side are unbeaten in their last five away league games and have kept clean sheets in three of those, albeit none in their last two.
Arsenal are in turmoil at the moment and need Alexis Sanchez's future resolved as quickly as possible so they can finally move on. Can they avoid an upset here?
Everton are without a win in their last six and have lost four on the spin. They have only scored in two of those six matches and the impact of Sam Allardyce's arrival appears to have worn off.
West Brom are now only two points adrift of safety after beating Brighton 2-0 last weekend. The Baggies have now on successive matches for the first time since August.
Alan Pardew's side have failed to score in four of their last six trips to Goodison Park but have still managed to pick up five points from a possible 18 despite that poor goalscoring record.
Everton would usually be clear favourites to win this match but their poor form suggests it will be a hard fought game for the Toffees. Expect a close encounter between two struggling sides.
