Jake Bidwell knows Charlton will be coming to Griffin Park determined to give their survival hopes a boost.
The Addicks are bottom of the table and have conceded 65 goals over the course of the season and Brentford will go into the game as favourites.
However, after their surprise reverse at relegation threatened Rotherham, the Bees will have to deal with another side that will come at them all guns blazing.
Bidwell said: “They lost in the last minute which shows they're scrapping and need wins. I'm expecting them to come at us all guns blazing. We need to repeat the performance we made against Wolves.”
Brentford like to play on the counter attack and Bidwell is hoping Charlton's style of play can suit them.
He added: “It might suit us. We'll analyse them in the week and see what they're about. They're scrapping for their lives and we've got to keep our season alive.”
The Bees beat the Addicks 3-0 earlier on in the season.
