“There are at least four other English clubs in the equation,” Football agent Barry McIntosh told Sky Sports News.
“But I think the location of London, the challenge at West Ham and working beside the likes of Scott Parker and Thomas Hitzlsperger have been very important factors in him considering the move.
“Right now, we think the best option, the most likely, and the one he’s most interested in is West Ham.
“I think for a foreign player of the magnitude of Riquelme, the lure of London is always going to be a deciding factor over any other club.
“So unless Arsenal come in then I think the most likely destination and the one Riquelme would be most interested in is West Ham.”
