Steve McClaren’s side saw a two goal lead slip against Birmingham over the weekend, with Bournemouth moving back to the top of the table, with the Rams in second.
“Low is probably not the right word. Disappointed and angry would be more like it, because we've got high standards,” said Grant.
“We'll take the result on the chin, though, and we'll look to use the anger, disappointment and frustration as fuel.”
Derby’s apparent blip in the fight for the title has probably come at the right time because there is still plenty of time for the team to react positively.
There’s plenty of time left for the Rams to get back into first place at the top of the table and to stretch out a lead over their rivals.
There is only one point separating the five teams at the top of the table, with Derby one of four teams currently on 66 points.
McClaren and other officials at the club will be working away furiously behind the scenes to try and find the cause of recent problems.
If they can correct things quickly then Derby can get back on track and look at stretching out that lead. No one is pulling away from the pack at the moment so there is everything to play for.
