Derby County boss Steve McClaren says their FA Cup tie with Leicester City is a test of their Premier League potential.
Derby have risen into Championship play-off contention since McClaren's return in October and beat West Bromwich Albion in the last round.
"We see it as a great opportunity to test ourselves against Premier League opponents. That's for the players, staff, and the club overall. If we can get the same performance and result as at West Brom we will be delighted with that," McClaren said.
"It is Leicester, just down the road, they will be bringing 5,000, atmosphere terrific, and it is a special game for the supporters. It is the FA Cup."
