Both West Ham and Crystal Palace are surely safe from relegation this season, but will look to take bragging rights in this London derby today.
The Hammers lie in 12th place, but their great run of form has tailed off somewhat in recent weeks, losing five of their last seven league games to make things ever so slightly tense at Upton Park.
With no clean sheet in the last eight games, Sam Allardyce's side are struggling to keep things tight at the back and fell apart against Arsenal in midweek despite taking a 1-0 lead at the Emirates Stadium.
Meanwhile, Palace have all but completed a miraculous escape under Tony Pulis, who has somehow guided the Eagles away from relegation trouble with four wins in a row - including a stunning 3-2 win at Everton in midweek.
There may not be much to play for on the face of this game, but three points would secure Premier League safety for both sides.
