Sean Dyche felt his squad passed a tough test as the Clarets saw off Blackburn in the Carabao Cup.
First half goals from Jack Cork – his first since returning to the club – and Robbie Brady effectively settled the East Lancashire derby.
And Dyche, who made eight changes to the side that lost to WBA at the weekend, was delighted as his side recorded a third straight win at Ewood Park to extend their unbeaten run against their old foes to seven games.
The gaffer said: “There were a lot of good performances tonight. A lot was made about whether I would change the team tonight and I made it clear, we are not resting players.
“It’s not about resting players. They don’t need a rest now, but we need everyone fit and sharp because the Premier League is a very, very tough league.
“You need to be physically and mentally right and what a great game to allow you that.”
Dyche added: “We are adding to the group with layers and this is a stronger group now. That doesn’t guarantee us anything going forwards, but there was a lot on show tonight, from players who we have brought in.
“Different players, for different reasons, showed what they are about tonight in what was an awkward game.
“This game goes beyond the cup, we all know that, so to get that experience was essential.
“They tried to get us on the back foot by putting the ball into the box from every position in the early stages, and we were very strong.
“As the game settled, we began to play and there was some really good stuff tonight, so 5,000 fans have gone home happy.
“For our fans it’s fantastic. They were in great voice again tonight and for that 90 minutes, we all understand what the outcome is; we have to win!
“Beyond that, the reality is we want to continue to grow in the Premier League, but I get it that the fans here wanted us to win, which we did, so I am very pleased.”
Jonathan Walters was the one downside to the victory, initially refusing to go off on a stretcher following a second minute challenge, but eventually making way with an ankle injury before the break.
Dyche added: “We are waiting to hear on Jon. He manged to play on and I wasn’t sure if I should make the decision for him.
“But he’s a very honest player and manged to play on. I’m not sure how right he was and eventually he had to come off, so we’ll see how he is, but we don’t think it’s anything too serious.”
