Hull boss Phil Brown has confirmed the club have made a "firm and substantial bid" for Fulham striker Bobby Zamora.
The Tigers have been unsuccessful in their quest to sign a striker this summer with Marc Antoine Fortune opting to join Celtic and Fraizer Campbell still stalling on a move to the KC Stadium despite the club agreeing a fee with Manchester United early last month.
Brown has since turned his attention to Zamora, who scored twice for the Cottagers in 32 league games last season.
"We've been active with regards to Fulham," Brown told the Hull Daily Mail.
"There is a firm and substantial bid on the table for Bobby Zamora. I'm waiting to hear from my chairman for the next step.
"There are substantial bids on the table for four players, one being Fraizer Campbell and the other being Bobby Zamora."
"There are a number of deals ongoing but am I anxious or nervous that people have not arrived yet? No I'm not."
