West Ham United boss Sam Allardyce wants one more signing this summer.

The likes of Lille forward Salomon Kalou have been heavily linked with a move to Upton Park and Allardyce has said it is likely only one more acquisition will be made.

"We're looking at securing one more player within the budget we've got this summer, and hopefully that will make us a little bit better than last season," he told talkSPORT.
