Eagles came on to conjure a fine winning goal in the final minute of stoppage time and move Wanderers to within five points of Brighton, who currently occupy the final play-off place.
Gus Poyet's men visit the Reebok Stadium on Saturday to take on a side unbeaten in seven matches and on a run of four consecutive victories.
Wanderers manager Freedman believes Eagles can be central to continuing Wanderers' purple patch and insists the 27-year-old former Burnley winger was only dropped to the bench due to the debilitating effects of a gruelling season.
"He's a talented lad and he's got that magic dust that we all look for," said the Scot. "He's got that spark, he's different.
"He's lost a little bit of that energy through me flogging him for 20-odd games or whatever I've done it for so I pulled him out of the team as a decision to benefit the whole group - not because I think he's lost form, just because I think it's the right decision.
"Luckily enough the opportunity fell to Chris who, if you know him, is a very confident character no matter what the situation is.
"He's a very chirpy lad who tells me how wonderful he is every day so I've got no doubt that if it does come his way he's going to sink it."
