David Moyes says West Ham will not make the mistake of underestimating Backa Topola when they walk out at the TSC Arena, a minute stadium with a 4,500 capacity.
The Hammers can stay top of the Europa League's Group A by beating the Serbian minnows on Thursday evening.
Yet Moyes insists they cannot be lulled into a false sense of security just because the ground holds fewer fans than most of those in England's National League.
'We respect all the opponents we play,' Moyes said on Wednesday night in Serbia.
