Charlton made a triumphant return to the Championship after a three year absence at Ewood Park on Saturday.
Efforts from Ben Purrington and Lyle Taylor sandwiched a bizarre own goal for Blackburn.
Lee Bowyer persisted with his three central defenders – Tom Lockyer on the right, skipper, Jason Pearce, in the middle, and Naby Sarr on the left.
Pearce had a fine afternoon, marshalling his troops as well as attending to his own defensive duties.
But Bowyer’s tactical master stroke was deploying Darren Pratley to man mark Rovers’ danger man, Bradley Dack. The former Gillingham favourite was rarely able to threaten.
Though the Addicks spent large periods of the game on the back foot, they restricted Blackburn to just two on target shots.
The Londoners took the lead two minutes before the interval, thanks to a move started and finished by Purrington.
The left-back intercepted a pass from Elliott Bennett and switched the ball to Jonny Williams.
Williams drove on and dinked a delightful little ball into the path of Taylor. The striker appeared to be bundled over in the area, but Purrington had continued his run, and was on hand to lift the ball into the roof of the net on the half volley.
Rovers levelled things up early in the second-half, courtesy of a bizarre own goal. A sloppy pass from Sarr saw Blackburn win a corner.
Bradley Johnson’s header was cleared off the line by Anfernee Dijksteel, but his clearance canoned into the net off the back of Dillon Phillips’ head.
Rovers went in search of the winner, but it was the visitors who struck gold. Again, the goal came from a corner.
Pearce’s towering header was touched home by Taylor.
Charlton saw out the remaining 13 minute – plus an astonishing 6 minutes of added time – without difficulty.
It was the perfect start for Bowyer,who was delighted with his team’s performance:
“I’m over the moon,” said Bowyer, “to come away from home to a good football club in Blackburn, they finished mid-table last year, so it was a good challenge for us.
“I said earlier on in the week that it would give us an idea of where we are. It proves it to the players, I said to them ‘Believe in yourselves because you are going to surprise teams’.
“Now this has happened on the first day I’m over the moon for them because now they might realise how good they are and what they are capable of doing.
“Don’t forget, we’ve still got to bring in four or five more players, that’s what I just said to them, we’re going to get stronger as well.
“They just keep going and fighting and competing for everything. For as long as we’ve got that we’re going to be ok.”
