Tottenham are chasing Nottingham Forest goalkeeper Karl Darlow.
The Mirror says Spurs may even be willing to sign 23-year-old Darlow, then loan him back to Championship promotion hopefuls Forest.
Sherwood is planning a shake-up of his keepers behind established first-choice Hugo Lloris after replacing Andre Villas-Boas - Brad Friedel will be 43 in May and is winding down his career, while little-used Heurelho Gomes is set to return to his native Brazil.
Darlow is one for the future, and represents a potential great deal for the north Londoners as he has been tipped to play for England.
