There have been two goals or less in six of Burnley's last seven away games and the same outcome in West Ham's last three home games. Burnley barely got out of their own half for 30 minutes as Marko Arnautovic and Michail Antonio in particular stretched them here, there, and everywhere - but without getting anywhere.
With defensive gaps opening up all over the place, substitute Chris Wood took full advantage with two more well taken goals - one courtesy of Hart's feeble parry - that left the home side literally battered and bemused.
West Ham are 14th in the standings, only three points above the drop zone, and Moyes expects the battle for top-flight survival to go down to the wire.
Despite a couple of delays, the match was played to a finish and afterwards Hammers manager David Moyes told Sky Sports: "We want the supporters behind us, but you can't cross the line and come onto the pitch".
"We would like to commend referee Lee Mason and his team of officials for their actions which, combined with the cooperation of players and coaching staff from both clubs, enabled the match to be completed".More news: Russian spy attack: British troops deployed to assist probe

"Actually the big thing was to say get on with it - keep playing".
By the end of the game only club legend Trevor Brooking was still in the directors' box as fans vented their feelings about how the East London outfit is run. After conceding 54 goals in 29 games, David Moyes' side now have the worst defensive record in the league. That much was clear from the abuse that was directed at Gold outside Swansea City's Liberty Stadium last weekend, and from the ongoing spat between various supporter groups over a cancelled march of protest.
While the official investigation of the incidents will be carried out by the FA, ... "If I thought there were no mistakes or no problems, I wouldn't have made any changes". At the prices I think it's worth backinng Palace to come away with a point at least.
"We were one goal down, in with a real good chance still - you know, the game was really tight".
"It's competitive, teams are doing everything they can to stay up". "It does make the atmosphere really tough to play in". Obviously we're not going to win every game.
