The Dutchman was part of Louis van Gaal’s Netherlands squad for the World Cup in Brazil and scored a vital goal after coming on as a substitute against Chile to help the Dutch top Group B.
Following the Canaries’ relegation last season, Redknapp is hoping the lure of Premier League football can tempt the 24-year-old to come to Loftus Road.
Redknapp revealed Fer is one of a number of midfielders the club are considering but admitted negotiations with Norwich have stalled.
"He's a player we like but I don't know where that one is at the moment," Redknapp told Sky Sports News.
"It's been ongoing for a while but there are other people as well that we are looking at.
"I think we need a couple of midfield players and we have got other targets we are looking at.
"We need to strengthen in a few positions really to be strong enough to really have a go at it this year."
Redknapp is also hoping to bring in at least one forward with Charlie Austin, Bobby Zamora and Loic Remy currently the only three recognised strikers at the club.
