Academy manager Nick Harrison was full of pride after he saw his side progress in the FA Youth Cup.
North End were the winners against a top academy side in Everton, and the manner of the victory was one that pleased the U18s boss.
"The lads were fantastic, the work rate was exceptional and that's how they have got the result in the end and I couldn't be more proud of them.
"I thought everybody, the lads who played and the lads who weren't involved, I thought they were a credit to the club and their families.
Having watched the first team take on Arsenal in the FA Cup just over a week ago, Harrison felt his players could learn a lot from that performance and feels that they took a lot from that game.
"We asked the lads to copy the first team, we actually watched the video back and I thought the lads took a lot from that and it just showed what you can do through hard work and quality.
"It wasn't just about the work rate and the effort, it was about what they did on the ball and I felt at times we could have had a couple of chances to put the ball in the back of the net but a lot of that came through hard work.
"I think if our lads can take that on into every game they play in their careers then they've got a great chance of being successful."
The win secures a place in the fifth round of the competition, with a home tie against Wimbledon up next.
Speaking of the last-16 tie, Harrison continued: "We've watched them already, they beat Hull City 3-0 so that's another Premier League club out and it's going to be another tough one.
"We are going to have to do our homework, we are going to have to work at it and hopefully the lads can put on another good show like they have done."
