Sportsmail can reveal the relegation-threatened Upton Park club are actively pursuing Keane and believe they can see off competition from Birmingham, Newcastle, Fulham, Aston Villa and even America's MLS to help him kick-start a career that has stalled in recent months.
With the 30-year old reluctant to uproot his family and in no mood to be dictated to by Tottenham over any decision on his future, West Ham chiefs are hoping to land him for barely half the £8million Birmingham were initially quoted.
Goodbye to all that? Keane is expected to make a move across London
They have made it clear they want him, irrespective of manager Avram Grant's precarious position, and are eager to begin the task of convincing him he can help steer them away from trouble in the Barclays Premier League.
Though Keane has privately indicated he would like his next club to be in with a chance, at least, of competing for honours, West Ham's negotiating team feel they can still entice him to Upton Park.
Precarious position: Grant
Any replacement for Grant would be handed funds this month for further signings, in a recruitment drive aimed not only at safeguarding their Premier League place for another 12 months but laying the foundations for an improvement next season.
A financial package including wages that rise to around £75,000 a week, with bonuses, put him beyond Fulham's reach, while reported interest from the MLS, and new franchise Vancouver Whitecaps in particular, has so far failed to materialise.
West Ham have also expressed interest in Boca Juniors winger andBirmingham target Pablo Mouche, 23, and have asked about free agent Pascal Feindouno, 29, a Guinea international midfielder who was released by Al-Sadd of Qatar last month.
