Tony Mowbray hopes Ben Brereton can show both sets of supporters how good he is when Rovers take on Nottingham Forest on Saturday.
The former Forest forward returns to the City Ground for the first time since making the move to Rovers last summer.
Brereton has found game time limited at Ewood Park, due to the form of strike duo Danny Graham and Bradley Dack, who have netted 30 times in all competitions this season.
But Mowbray has high hopes for the 19-year-old, who he believes will be a big player for the club in the future.
"I've always felt when players go back to clubs that they signed from or a club that they've been at in the past, you have to weigh up the personality of the player, because sometimes those events can be almost too big for an individual and they get too wrapped up in the crowd and the atmosphere and they forget to play the game," said the manager.
"With Ben I'm not sure. I've talked a lot about Ben in the past. I think he's a wonderfully talented boy. Maybe this is an occasion for him to show the people of Nottingham what he can do, although I feel as though he has already done that.
"Hopefully in time he will show the people of Blackburn what a talent he is and why the investment was put into him.
"At some stage that will come. If it's this weekend, then great for him. If it's not, he's very much in the long-term plans of this football club.
"As I've always said, somewhere down the line, everybody will be saying 'wow, what a player' and we'll be fighting off bids for him.
"I know that that time will come at some stage. Let's hope he gets an opportunity on Saturday and he can show everyone how good he is."
Rovers won 1-0 at Forest on their last visit to the City Ground, two years ago this month, and Mowbray admits that Brereton's performance that day really caught his eye.
"I knew about him, but I could feel the quality and what he brought with the ball and how big he was, regarding his size, that day," added the Rovers boss.
"Running with the ball, travelling with the ball, beating men, put him in my mindset really.
"Sometimes that happens in football. As the coach, generally I'm looking at my own team, but that day Brereton did pick the ball up and run with it a lot and gave us a lot of problems.
"Let's hope it's a good day for Ben and a good day for our football club."
