West Ham chief David Sullivan insists Diafra Sakho is not for sale - for now.

The striker's future under Slaven Bilic is in doubt after missing the club's pre-season USA tour amid reports that he has handed in a transfer request.

“He is not for sale until we get players in," Sullivan told the Mirror. "Until we bring strikers in, we simply cannot let strikers go.

“James Tomkins was different because we had a surplus in the centre-half department.

"But until we get at least a couple of strikers we can't let any forward go.

“I am a little concerned because I'd like to have signed one by now. But it is what it is."
