The rapid winger was signed from Sheffield Wednesday this summer and Powell clearly feels that it is a good bit of business for the Reds.
"Michail Antonio was an inspired signing," he said to the Examiner. “They’ve got players who are very good at this level, but it’s up to us to carry on the work we’ve been doing and impose ourselves in what I’m sure will be a lively game."
The Huddersfield boss will be plotting to stop Antonio being at his best at the weekend, though.
Although the powerful wide-man has scored seven goals already this season, Powell will be confident that his side have the ability to keep him quiet.
The Terriers have improved hugely under the guidance of Powell, climbing out of the relegation zone and into a mid-table spot and they will be looking to continue their fine run of form against Forest.
Stuart Pearce's men started the season in blistering run, climbing to the top of the Championship in the early stages.
However, they have struggled more recently to pick up points - with the club failing to win any of their last eight games in all competitions.
They know this a run which cannot continue for much longer if they are to meet their expectations are mounting a promotion push and, therefore, will be desperate for the three points on Saturday.
