One of the companies its commercial director Richard Arnold has written to is Sahara Group, an Indian conglomerate active in finance and media among other sectors.
Abhijit Sarkar, a spokesman for Sahara, told Reuters: "We can confirm that we have received a proposal for team sponsorship, it is an elaborate one."
AIG, which had to be bailed out by the US Government last year after massive losses on derivative contracts, is very unlikely to renew its sponsorship.
The club spokesman Philip Townsend told Bloomberg News today that the club is confident it can better the revenue generated by the AIG deal.
