West Ham United boss Sam Allardyce cannot put a return date on Andy Carroll's recovery from a hamstring problem.

With the club still yet to put a definitive time-frame on his hamstring injury Allardyce is hoping he could welcome Carroll back earlier than expected.

"We have got no time on it really," he said. "It will be a maximum of six weeks but he is improving well so we continue day-by-day and look at every day and see what type of improvement we have got and go from there.

"If there is a possibility we can get him back quicker we will be trying our best."
