Cardiff City goalkeeper Neil Etheridge is interesting West Ham.
The Sun says a deal with Middlesbrough for Darren Randoplh may be more expensive than West Ham thought for the Republic of Ireland international.
So Etheridge, 29, has emerged as a leading alternative, although the Welsh side would also want a decent fee.
The Philippines No1 is a late developer who was one of the Bluebirds' most consistent performers at the top level before they rejoined Boro in the Championship.
But the Hammers' immediate priority is appointing a new manager following Manuel Pellegrini's sacking just minutes after their 2-1 home loss to a much-weakened Leicester side on Saturday night.
