Rosler was sacked as Leeds boss earlier today, after having just 12 games in charge, and Redfearn feels that the German boss will be frustrated.
Redfearn, who has taken over the job at Rotherham United since leaving Elland Road, says that Leeds needed stability, but he was keen not to place too much focus on the goings on at his former club.
"I don't want to comment too much on what's happening, but to build anything or to create anything you need stability," he said in the Daily Star.
"It's probably frustrating for Uwe because he will have had his plans and put things in place as did I last year and got them to a certain situation where you think you can take them on.
"But they do it as they want to do it. I have got a lot of friends at Leeds and I wish them every success apart from when they play us.
"But to be honest with you I am more interested in Rotherham United. This is where I am at, this is what I am excited about."
In an unexpected twist, Steve Evans, who was Redfearn's predecessor at Rotherham, appears to have landed the Leeds job following Rosler's departure, according to a report in the Daily Mirror.
The job that awaits him at Elland Road will be a tough one, especially as the reaction to his appointment has not been a positive one.
Leeds are currently in 18th place in the Championship table, and they have not won any of their last three matches.
Evans' first fixture in charge of Leeds is expected to come on Wednesday night, when the Whites take on Fulham at Craven Cottage.
