Development squad boss Damien Johnson was pleased to see Rovers record another win but less impressed with the performance against Norwich City on Monday night.
The Under-23s were slow starters under the lights at Ewood Park, with the visitors dominating the early exchanges.
As the first half wore on Rovers improved, culminating in Lewis Mansell heading the home side in front just before the break.
The second half was a more even affair with Rovers completing the victory four minutes from time thanks to a Connor Mahoney penalty.
"The result is pleasing, but it isn't just about the result for us, it is about the performance as well," Johnson told Rovers PlayerHD after the match.
"There were certainly elements of that that we weren't happy with, the first 15-20 minutes we lost our way and made too many mistakes and conceded too many chances which isn't like us.
"I said to the lads that if you keep doing that against good teams then on another night you'll get punished and you could be two or three goals down. So that's certainly something that we've got to learn from.
"As the half went on we grew into it and we got better, we got it wide and Bennett and Mahoney caused them problems. It was a good time to score just before half-time.
"There were elements of our play that were good but overall there is definite room for improvement."
The Under-23s are back in Premier League 2 action next Monday when they travel to take on Swansea City.
