West Ham United - Crystal Palace live updates

FULL TIME: West Ham 1-3 Crystal Palace

One minute remaining as Speroni falls on the ball and takes his precious time…

Palace can go five away matches undefeated in the PL era for the first time in the club's history. The last time they went five undefeated in the top flight away from home was between December 1991 – February 1992 (6 matches).

Cross from Jenkinson well cut out by Kelly. Sheer weight of numbers now for Palace.

This 3-1 scoreline would be Crystal Palace’s biggest League win against West Ham (all divisions) – beating the 2-0 Div 1 away win in April 1992.

It falls to Kouyate in the box and he goes down! Appeals for a pen but would have been harsh. FIVE added minutes.

West Ham laying siege to the Palace goal. Sakho with the header but easy for Speroni.

GREAT SAVE! Dipping shot from Valencia well saved by Speroni. Clawed out of the top corner.

West Ham have managed just one win in their last nine PL matches (W1-D5-L3), v Hull City on 18 January (3-0).

FIVE MINUTES REMAINING: Plus whatever stoppage time we have. Probably around three minutes.

STAT: Glenn Murray is the fourth Palace player to have scored more than once in a PL London derby for the Eagles (after Dwight Gayle v Fulham in May 2014; John Salako v Arsenal in Oct 1994 & Eddie McGoldrick in Dec 1992) – all four instances have come away from home.

Palace sub: Bolasie off for Ledley.

CHANCE WEST HAM! It’s a great chance for Jenkinson from Noble’s ball but an equally good save from Speroni to deny him before Downing fires wide.

Enner Valencia has scored his first PL home goal – his first three for the club all came away from home (last in 2-2 draw at Stoke, Nov 1).

Sakho heads over the bar from Jenkinson’s cross. The ball in was hit hard but still a half chance.

Valencia with the bit between his teeth now and he wins a free kick off Puncheon. Kelly forced to concede a corner…

GOAL WEST HAM! Valencia scores his first league goal at Upton Park, his excellent shot from just outside the box beating Speroni via the post. Can they do it?

Sakho wriggles through in the Palace box and his goalbound shot is blocked out for a corner at the last moment.

No urgency from West Ham. Time already running out.

West Ham have conceded three PL goals in a London derby for the first time since their 3-1 defeat at Arsenal in April 2014; and first time at Upton Park since their 3-1 home defeat against the Gunners in Dec 2013.
