Derby's Irish captain Richard Keogh has vowed they will hit back after their mini slump.
They host Huddersfield tonight after surrendering the lead at Brentford to lose 2-1 on Saturday, their second straight league loss, which saw them knocked off the summit of the Sky Bet Championship.
Keogh admitted those two games have been a learning curve and they have not hit top form.
"Maybe as a group, we aren't quite mature enough to do that at the moment," he said.
"We learned a bit about ourselves as a group, that we need to hit those standards a little bit higher - especially when we hit the top of the league.
"It's been a good learning curve for everyone, but we will come back stronger and we have got a good group, a good squad.
"I'm looking forward to the upcoming two home games and we will be aiming to get good results."
Fifth-placed Derby are three points behind leaders Watford, who go to Birmingham with midfielder Gianni Munari warning their title rivals the Hornets will get even better.
They are unbeaten in nine games after their 3-1 win over Millwall on Saturday.
Bournemouth have moved up to second ahead of their trip to Sheffield Wednesday.
Third-placed Middlesbrough welcome Norwich, who sit sixth, and either team could go top with a win and if other results go their way. ust three points separate the top six, with Blackburn a further point adrift in seventh as they head to Millwall.
Wolves go to Ipswich for a reunion with their former manager Mick McCarthy, who took them to the title in 2009.
Third-bottom Bolton host Cardiff with chairman Phil Gartside in takeover talks with a Thai consortium. Leeds host Charlton, Wigan go to Brighton and Reading travel to Rotherham.
