Leeds current squad is one of the youngest in the Championship and Redfearn believes that the side have struggled recently due to a lack of experience.
As a result he says that Championship veterans will be on his list of priorities in the upcoming transfer window, with Leeds expected to be active in the transfer window.
Attracting players could be tough for the Whites, as they are under a transfer embargo, but in this piece we take a look at three players whose contract expire in the summer, who could make good additions.
The striker's career has stuttered recently, but he would bring a lot of quality to Leeds' starting line-up.
Blessed with pace and a clinical finish, Maynard has proven has class at Championship level before, with his form at Bristol City exceptional.
He has not been at his best since 2012, but he needs to find a new home and Leeds could be the perfect fit.
Redfearn's team need a reliable finisher and if they can bring Maynard to the club they would be able to build their attack around his talents.
A robust and commanding centre-back, Mills should be on Leeds' wishlist this summer.
He has Championship experience, but he is still only 28 and he could bring steel to the Whites' defence.
With Sol Bamba likely to join-up, Mills would be a great partner for the Ivorian and the pair could help form one of the most sturdy looking back lines in the Championship.
Stephen Quinn (Hull City)
A tireless worker, Quinn's energy and desire would fit in well with a Leeds side who are well structured under Redfearn.
The Whites have built their success around the commitment of their players and there are no question marks over Quinn in this respect.
Able to play centrally or out-wide, the Republic of Ireland international could cover two positions and his creativity would enhance Leeds' attacking threat considerably.
