James Collins feels West Ham United already have strong defensive options.
West Ham boss Sam Allardyce is seeking a new left-back signing.
"Defensively we did alright last season," said Collins.
"We had 14 clean sheets so like the gaffer has said we need to concentrate on scoring more goals - that is why he has brought in Teddy (Sheringham) to improve us in the attacking half so hopefully we can score more goals and get off to a better start.
"We (the defenders) have all been here a while now and know each other's game very well so whoever is asked to play knows what is expected of them - it is a great group of lads so hopefully we can start off well and kick on from there."
