Cheltenham goalkeeper Scott Brown has called on his team-mates to remedy their set-piece woes.
The Robins surrendered a 3-1 lead to lose 6-4 at Rotherham at the weekend and eight of the 11 goals they have conceded so far this term have been from dead-ball situations.
"We need to put a stop to it straight away or it will end up costing us more points than it has done already," Brown told the Citizen.
"We did work on it last week, but we need to sort out our markers better than we did at Rotherham.
"It's very frustrating when you let in six and wonder what more you could have done.
"All the top teams deal with set plays and we have to be much better at stopping them."
