Fulham assistant manager Christian Damiano has told his team that after they beat Arsenal, Chelsea and Spurs, do not underestimate Charlton.
He said: "They are a good side with good players - and their confidence has risen after wins against good teams like Arsenal, Chelsea and Tottenham.
"They are well organised and mentally they are never beaten. They are strong with good players.
"We are confident we can deal with them but we know it will not be an easy match."
Fulham have no new injury worries for the Premiership clash, although Steve Marlet is still out with a knee problem.
John Collins says the side are desperate to gain revenge for a frustrating match against Charlton at The Valley earlier in the season.
The two teams drew 1-1, even though Fulham had almost all the play, now Collins says his teammates are determined to put the record straight.
He said: "That game at the Valley was a game we dominated from start to finish and we were desperately disappointed to come away with only one point.
"It was very frustrating but that was four months ago and it's a different ball game now. We are a lot more confident and experienced these days and we'll be going all out for victory."
