Chairman Milan Mandaric believes Sheffield Wednesday will use the defeat to Charlton as motivation in their bid for promotion.
Gary Megson's side went down 1-0 to the League One leaders, slipping to a first home loss in the league this season.
The Addicks moved eight points clear of the fourth-placed Owls with that victory, but Mandaric has backed Megson to rally the troops and keep pace with Chris Powell's side.
"I still believe in our team, the players and the management and we still have enough games to be successful this season," he told The Star.
"We have to approach every game to the best of our capabilities and keep grinding the points out.
"The players are strong mentally and, if anything, they will use it [the defeat] as motivation going forward. We have strong people and if anything they are going to try extra hard to get back on the road."
