Brentford boss Nicky Forster praised his side following the 1-0 win at Charlton and admitted they were able to capitalise on the negativity surrounding their London rivals.
Leon Legge struck in the 89th minute when he headed home Myles Weston's corner to put another massive dent in the Addicks` promotion hopes.
Charlton now lie 13 points adrift of the top six and have gone seven matches without a win, leaving their disgruntled fans to make their feelings known at the final whistle.
Forster said: "The Valley at the moment perhaps isn't the best friend for Charlton. They seem a little bit anxious about playing there.
"We moved the ball well, I think we played some really good football at times. There were some really good performances out there, not least from Leon Legge, who in the second half was immense.
"Maybe we rode our luck a little bit when the ball hit the bar and Richard Lee pulled off a fabulous save but over the course of the 90 minutes I thought we just edged it in a very good game."
