Millen's view: Preston away 4-0
The Robins shrugged off any mounting pressure to canter to victory against the league's bottom team.
It was a good day at the office for City's strikers as goals from Andy Keogh, a brace from David Clarkson and another strike from top scorer Brett Pitman secured our biggest win of the season.
And Millen was understandably elated with his team's performance, after failing to hit the net for five games.
"It's been a tough run for us and to come here and score four goals was the perfect performance," he told bcfc.co.uk
"We started well and only lost momentum when Caulks [Steven Caulker] suffered a cut above the eye and had to go off for stitches.
"We scored early goals and early goals change games. With ten men for a short time, we produced some great defending and a few good challenges and saves.
"I thought we could on counter them with a change of shape. I wanted us to get the next goal and kill them off.
"With Brett [Pitman] on there, we matched up against them. We missed two chances and they saw two cleared off the line.
"The second goal let the confidence flow amongst our lads and you could see them flourish.
"It's the way we opened them up that was most pleasing. We haven't been creating much recently and to score four goals was a dream."
Millen also had special words of praise for young defender Joe Edwards, who made his senior debut as a second half substitute.
"He's got a bright future and it was nice to give him a debut in a 4-0 win," the City boss added.
