Tottenham are making a bid for West Ham United defender Anton Ferdinand.
But new Tottenham manager Juande Ramos is ready to up the fee to £6m to land the former England Under-21 star.
Hammers boss Alan Curbishley has been told he must trim his huge squad before he can go on a summer spree.
West Ham have six centre-backs on the books and with James Tomkins, 19, pushing for a first-team spot, Curbs may let Ferdinand go.
