Tottenham are planning a £6 million bid for West Ham United goalkeeper Robert Green.
Ramos has had Green watched over the last month and is now deciding whether to test the Hammers' resolve with a bid.
The two keepers have had contrasting seasons with Robbo being dropped by both England and Tottenham, while Green has been outstanding.
Green, 27, signed a new deal last year and is understood to be happy at Upton Park.
But boss Alan Curbishley will pull out all the stops to keep him after being made aware of Tottenham's interest.
