However, the same cannot be said of the Rams, who are yet to register a win from open play in their three matches ahead of their trip to Kenilworth Road.
Eyebrows were raised when Nathan Jones was given the opportunity to return to Luton Town in May, less than 18 months after he had left the Hatters to endure a disastrous spell at Stoke City.
However, as it stands, the appointment by the Luton board looks inspired, with the Welshman recording seven wins and four draws from his first 12 matches in charge.
Survival in the Championship has been followed by reaching the third round of the EFL Cup, setting up a glamorous tie at home to Manchester United next week.
That said, full focus will be on trying to build on a potentially-crucial 1-0 success last weekend at Barnsley, another team who miraculously avoided the drop last season.
James Collins has been the star of the show thus far, netting each of his four goals in all competitions during the final quarter.

Sluga; Cranie, Pearson, Bradley, Norrington-Davies; Berry, Mpanzu, Rea; Cornick, Collins, Lee
Derby County possible starting lineup:
Marshall; Wisdom, Davies, Clarke, Forsyth; Rooney, Bird; Whittaker, Sibley, Knight; Marriott
We say: Luton Town 2-1 Derby County
Jones will be desperate for his side to maintain the momentum which has been generated in recent weeks, and we expect them to do just that. Derby are struggling to get anything going right row, with a game against opponents who will relish their underdogs tag coming at completely the wrong time.
