When asked what he'd said to the players at full-time, Moyes responded: "I've told them that we are all sticking together - we're going to stick out chest out and go again".
As with the majority of Burnley's games, there is unlikely to be many goals shared between the two sides.
The West Ham boss is without Winston Reid, Sam Byram, Andy Carroll and Pedro Obiang, while Arthur Masuaku is suspended.
"I think there was a couple of games where I wasn't quite so happy that we didn't do as well as we should have. It's going to be tight and probably go down to the last day for many teams". We are one of about seven or eight teams, or perhaps even more, with only three to six points between them, which shows how hard the Premier League is. Providing neither an effective attacking outlet or a sturdy defensive base for their teammates, Moyes is likely to persist with these ageing stars for this match, however, its increasingly looking like their respective final season in the English top-flight unless they can drastically turn around their current form.
Former West Ham great Trevor Brooking was left nearly alone in the directors' box. Dyche focuses most his team's attacks down the wide areas of the pitch to supply ammunition to his forwards. The Kiwi scored the victor against Everton last weekend and contributed a late equaliser against the Hammers earlier in the season. A £30,000 fine was handed to the club for breaching the anti-doping rules laid down to all clubs in the league.

Ashley Barnes broke the deadlock midway through the second half at London Stadium and after that goal and a further two from substitute Chris Wood, West Ham supporters entered the field in worrying and regrettable scenes.
The Baggies are now eight points from safety with nine games to play, with Stoke, Crystal Palace, Southampton, Newcastle, Huddersfield, West Ham, Swansea, Bournemouth, Everton and Brighton separated by just seven points.
But things quickly turned sour.
Wood scored a third goal as West Ham imploded on and off the pitch, with the team three points above the relegation zone and no doubt facing serious repercussions from the game's authorities.
