The Daily Mail says Etoâ€™o will join on a Â£7million one-year deal.
Etoâ€™o, the 32-year-old Cameroon forward, is taking a huge pay cut from the Â£17m a year that made him the worldâ€™s best paid footballer at Anzhi and will sign on a free transfer.
However, Anzhi are understood to have sweetened the deal by giving Etoâ€™o a multi-million-pound lump sum to get him off their wage bill.
Eto'o arrived at London's St Pancras station on Wednesday night, where he was pictured with super-agent Pini Zahavi, and is due to have a medical at Chelseaâ€™s Cobham training ground before finalising terms after his advisers held talks on Wednesday.
