Alex Pritchard's second-half winner on Saturday afternoon ended a run of four games unbeaten for Leeds United.
But the Yorkshire side's performance levels were far from up to scratch. Redfearn's men lacked balance and Leeds were toothless in the final third yet again.
Should the Leeds boss, then, consider changes in personnel ahead of Tuesday night's trip to Reading?
Youngsters Alex Mowatt and Adryan were first-team regulars at Elland Road earlier this season, while Mirco Antenucci is the club's top scorer. None of the three featured against Brentford - but could Redfearn look to bring them back into the fold?
The biggest risk, of course, comes with Leeds playing away from home at Reading. The Yorkshire side were unbeaten during their previous four games so drastic changes shouldn't be enforced.
Mowatt's creativity is better suited at Elland Road, while Antenucci has been off form for some time.
But playing Billy Sharp down the left clearly didn't work for Redfearn against Brentford. Nor did Steve Morison have an effective game in front of the Leeds fans.
Where 20-year-old Adryan is concerned, the Brazilian is the biggest enigma of all. He obviously has the talent to win games for Leeds - but the combative nature of the Championship is limiting his impact.
There's certainly a case, then, for all three to remain on the sidelines once again considering all of the above.
But what Redfearn has to ask himself is whether those he's been playing instead are really much of an upgrade considering their recent form.
