The former Sheffield Wednesday player says that he believes both teams will be able to mount a promotion push, and he is not surprised by their recent good form.
"I thought surely it's just a matter of time before results start to flow at Derby," he said. "They are really starting to hit their straps now, and they are really playing as a team now. I'm not surprised they have started to turn things around.
"And Wolves, we expected them to come on strong, too. Kevin McDonald is a big influence in midfield, Benik Afobe is an important player and Danny Batth, coming back from injury, is a big plus.
"Everything points towards Derby and Wolves coming on strong and those two clubs, I do suspect, will challenge for the top six."
Derby and Wolves both struggled for form over the early part of the campaign, but they have found their rhythm now and are starting to show why they were both considered promotion favourites over the summer.
Paul Clement's men have not been beaten in any of their last five matches, and they have climbed up to seventh in the Championship table as a result.
Wolves, meanwhile, have picked up seven points from their last three games, and only conceded once during that time.
It sets up an intriguing clash on Sunday, with the victor of the contest likely to move into the play-off places for the first time this season.
