The 57-year-old former Rovers skipper took the reins on Tuesday after Saunders was appointed manager of Wolves on Monday.
"Hopefully we'll have a good week [in training] and finish it with a win at Stevenage," Flynn told the Sheffield Star.
"I've certainly got one thing going for me; whatever happens next at this club, there's some really good players here.
"It's an unusual situation we find ourselves in.
"It's not often that you're looking for a new manager when you're top of the league.
"But in football you shouldn't be surprised by anything. It didn't surprise me.
"I got the call [to take temporary charge] and I was delighted to accept it."
