The former Tottenham Hotspur manager moved Rose to left-back during his time at White Hart Lane.
Rose had signed from Leeds United the previous summer as an attack-minded player, and was deployed higher up the pitch in his early appearances for Spurs.
It was under Redknapp that Rose was dropped back into defence and the 25-year-old has made the position his own over the past few seasons, following a successful loan spell at Sunderland.
Speaking to TalkSPORT's Alan Brazil Sports Breakfast show on Friday, Redknapp insisted: "I always felt Danny could play left-back for England.
"He was a left winger when I first went in and as a left winger he was always short of that extra little bit of something when he got it wide."
Rose, who considered representing Jamaica last year, now looks certain to travel with the Three Lions to France this summer, despite competition from Ryan Bertrand and Luke Shaw, who is set to return from injury before the end of the campaign.
The Yorkshireman earned his second cap during Tuesday's 2-1 defeat to Holland at Wembley.
