Adryan has struggled for regular action at Leeds United since the turn of the year.
The Brazilian's arrival at Elland Road last summer was greeted with much anticipation, but he has failed to live up to expectations during his time with the Yorkshire club so far.
Adryan has shown his ability in flashes, but his failure to find any consistency has seen him fall down the pecking order and Redfearn is looking for him to improve considerably before he puts him back into the starting line-up.
“He’s got to start playing well to get in,” Redfearn said. “It’s that simple. He’s got to do well and play well.
“What’s happening here now is that everyone realises you’ve got to compete and play well to be in our squad. We’ve been striving for that for the last two or three months and it’s the only way you make your team and your club better."
The 20-year-old loanee has not made any appearances since an FA Cup clash with Sunderland at the start of January and, unfortunately for him, his time on the sidelines has coincided with one of Leeds' best runs of results of the campaign so far.
Redfearn's men have lost just one of their last six matches in Championship action and they have climbed up to 17th as a result.
A key part of this turnaround has been the dedication of their more attacking players, and Adryan may not fit into their system the way it is at the moment.
What Adryan can take confidence from is that Redfearn will never write a player's chances off entirely, though - as he has shown with Scott Wootton, Casper Sloth and Steve Morison in recent times - and the Brazilian will determined to follow in their footsteps and force his way back into starting contention over the coming weeks.
