Allardyce wants one more player to bolster his squad before the window closes

West Ham United manager Sam Allardyce has been given permission to sign "one quality player" before the summer transfer window closes on 1 September.

The Hammers have made seven signings already this summer but a six-strong injury list which includes Andy Carroll, who won't play until at least November following ankle surgery, will force Allardyce back into the market.

And the 59-year old has confirmed that West Ham co-owners David Gold and David Sullivan have agreed to the club signing at least one more player in the final four days of the window.

"Speaking to the chairmen we have enough [funds] for one quality player and that's a possibility before the window shuts," he said.

"At the moment I can't see anyone going out the other way. One more player in the squad and we'll have a good one, and hopefully a fit squad that will stay that way and get results.

"When it shuts, we've got an international window which is coming for us at a good time based on those injuries. The training we can do in that period will get some of the lads fitter than they are and hopefully we'll have some of the injured players recovering for Hull City."

Mauro Zarate, Chiekhou Kouyate, Aaron Cresswell, Diego Poyet, Enner Valencia, Carl Jenkinson and Diafra Sakho have already joined West Ham this summer, making the east London outfit among the busiest in the Premier League.

Zarate and Sakho have already partly repaid West Ham's investment with goals on their full debuts against Crystal Palace and Sheffield United respectively, but with Valencia still regaining full fitness the club are desperate for more forwards.

After flourishing with Ecuador at the World Cup in which he scored in each of his nation's three group matches, Valencia only made his West Ham debut in the League Cup on Tuesday and could yet be left out against Southampton this weekend.

"We give the players six weeks in pre-season to get themselves ready, but when a new player comes in everybody expects him to be ready in ten days or two weeks," Allardyce warned.

"It's my job to make sure he is 100 percent fit to be ready to go on a regular basis, and once he does that, we hope he proves himself as soon as he possibly can to show the goalscoring ability we know he's got."

Following Allardyce's comments, co-owner Gold confirmed his support of his manager in the window by writing on Twitter: "Still hoping to bring a new signing before the window closes. dg."
