The Leeds boss was impressed by his side's performance against Rovers but feels there is scope to add to the current squad.
In fact, Redfearn went as far as saying Leeds were 'excellent' for 60-70 minutes at Ewood Park.
The Yorkshire side took a first-half lead through Souleymane Doukara, before Jordan Rhodes struck twice for the home side late on - his second coming from the penalty spot.
The defeat denied Redfearn back-to-back wins as permanent Leeds boss but the 49-year-old was nevertheless impressed with his side's overall display.

Despite being pleased with his side's performance, however, Redfearn has not ruled out new additions to the squad before the loan window closes this Thursday.

Leeds United's defeat leaves them 16th in the Championship, with Blackburn now up to sixth in the table, meaning they are in the play-off places.
Next up for Leeds are league-leaders Derby County at Elland Road, before a visit to Mick McCarthy's Ipswich Town. The following week, Redfearn's men will come up against former striker Ross McCormack, now of Fulham.
