West Ham are preparing to submit a fourth bid worth around £6 million for Norwich City striker Grant Holt, Goal.com understands.
The newly-promoted Premier League club have had three previous offers, worth £3m, £4m and £5.5m, rejected by the Canaries.
The Hammers are ready to make what is likely to be a final attempt to prise the 31-year-old away from Carrow Road by making a bid that matches the club's valuation.
Around £4m is expected to be offered up front, with the rest made up of target-related add-ons, such as appearances.
The Canaries rejected a transfer request from Holt in May and his representative has said that the forward will shortly hold face-to-face talks with new manager Chris Hughton, but the player is believed to be desperate to leave the club after falling out with chief executive David McNally.
Holt, who scored 15 Premier League goals last season and is also attracting interest from his former manager Paul Lambert at Aston Villa, claims he was told by McNally that he did not deserve a new contract because he was too old.
West Ham are willing to nearly treble Holt's current salary of £15,000 per week to £40,000 per week, the limit of their newly-set salary cap.
East London remains the most likely destination for Holt, despite Lambert's appointment as Villa manager after leaving East Anglia earlier in June.
Irons boss Sam Allardyce wants to add greater firepower to his squad, even though the current roster of forwards at Upton Park boasts Carlton Cole, Nicky Maynard, Frederic Piquionne and Ricardo Vaz Te.
Holt joined Norwich from Shrewsbury for £400,000 in July 2009 and has been voted as the club's player of the year in each of his three seasons at Carrow Road.
He played a key role as the Canaries achieved back-to-back promotions, before helping them to a mid-table finish in the Premier League last season.
