THE last clash at Pride Park was dominated by the heroics of Lee Camp, who returned to haunt his former club by making a vital late penalty save.

But while many Forest fans mourned his departure from the City Ground when his loan spell expired, Smith has more than filled the void.

The former Southampton and Brentford man has regained his best form, keeping a string of clean sheets.

The Reds defence has largely been solid but Smith had to work hard for his clean sheets against Manchester City, Charlton and Plymouth.

And while Billy Davies may yet sign another keeper to provide competition and cover, Smith would be very unlucky to lose his place.

Carroll has vast experience, having enjoyed spells with Manchester United, Wigan and West Ham after starting his career at Hull.

The 31-year-old has been an important player this season, even if he has only kept two Championship clean sheets – that has been more to do with Derby's fragile defence.

He spectacularly fell out with former boss Paul Jewell in December and was suspended following the defeat to Crystal Palace.

The shot-stopping abilities of both players are likely to have a big say in deciding which team secures a place in the fifth round.
