Both David Vaughan and Sebastian Larsson came good with stunning strikes within six minutes of each other to secure victory in Martin O'Neill's first game in charge, and the full-back thought that the Black Cats thoroughly deserved to win.
"We dominated large parts of the game - Blackburn didn't get over the halfway line that often in the second half and we put them under so much pressure," Bardlsey recalled.
"We needed that killer instinct and finally we got there in the last 10 minutes. It doesn't matter when you get the goals as long as you end up with three points on the board.
"Something special was needed and it was a great strike from Vaughany to get us level."
The ex-Manchester United trainee won the free-kick that Larsson converted when Mauro Formica stopped his attempted pass with an arm and admitted he thought his teammate might have something up his sleeve.
"When the referee blew for handball, I was quite delighted because I knew the ability Seb has," he continued. "He showed great technique to get the ball up and over the wall and into the net.
"Seb had a tiny gap to hit because the keeper had that side covered. Fair play to him - it was a great strike. The free kick really was phenomenal."
