Leeds United were known to have been on the look out for a winger last season.
Redfearn was in charge of Leeds for the bulk of last season, and he felt that Ward would have been a good addition for the squad.
However, no deal was sanctioned, and he has now linked up with the winger at Rotherham, after recently landing the managerial job at the New York Stadium.
"When I look back to when I was at Leeds, I would have taken a lot of players at Rotherham," he said. "Danny Ward, I rate really highly, and he was someone I really wanted to take at Leeds. He's just one example, there are five or six others in the squad, too."
Redfearn made no secret of his desire to sign a winger when he was with Leeds, but he was left short in that position all season.
In the end, Redfearn had to move Sam Byram forward, to play down the right-hand side, with a lack of other options in his squad.
At the time Redfearn was looking at Ward, the winger would have likely have been at Huddersfield Town, as he only moved from the Terriers to Rotherham in January 2015.
During his time with the Millers, he has scored three goals in 20 matches, but a lot of these appearances have come as a substitute.
