Chris Wood and Dwight McNeil were on target as Burnley secured just a second win in ten league games with an impressive 2-0 victory over a resurgent West Ham side.
Determined to bounce back from their crushing defeat to Everton last time out, Sean Dyche's outfit threatened early on through Ashley Barnes, who scuffed his close range attempt wide - in one of many warning signs from the hosts.
Burnley opened the scoring in the 15th minute, when Ashley Westwood's pinpoint cross was headed by Ashley Barnes into the path of his strike partner Chris Wood, whose half-volley flew past a helpless Lukasz Fabianski.
