Blackburn manager Michael Appleton said his players would have to learn to deal with criticism from the Ewood Park faithful after his first game in charge ended in a 2-1 defeat to Charlton.
Dale Stephens' stunning strike put Charlton ahead before Jordan Rhodes headed in his 15th league goal for Blackburn. But the Addicks snatched the points through Yann Kermorgant's firm header, and the end of each half was greeted with boos from the supporters.
"I think the atmosphere in the stadium was a strange one so I think they've got to deal with that," Appleton said. "They're a big fish in a smaller pond to what they were in last year in terms of the Premier League.
"There's added pressure that goes with that and they're going to have to cope with it because we have three home games coming up in quick succession and it's going to be a challenge for everyone.
"I'm sure the supporters just want to see a committed performance from the players. I think they huffed and puffed today but I'm not sure how committed they were once we conceded the second goal, which was a disappointment."
Charlton boss Chris Powell was delighted that his players were rewarded for their positive attitude after a second consecutive win on the road, and the Addicks' first at Ewood since October 2003.
"I think we've been very positive away from home this season," Powell said.
"We've had some good results on the road and the team warranted their places after their performances last week. We were very positive in our mindset and I think it showed today."
Only Hull and Watford have better away records than Charlton this season, and Powell was pleased with how his side dealt with Rovers having a new manager.
He said: "We're extremely pleased and I'm very proud of the players today because we had the factor of a team having a new manager and looking to impress the new manager and we've known over the years what normally happens so it was up to us to make sure we got our tactics and performance right and ultimately over the 90 minutes, we did."
