Powell is already planning for next term's promotion push after seeing the Addicks slip way off the play-off pace since the turn of the year.
"The pressure and burden of getting out of League One is not easy," said Powell.
"Look at Leeds, it took them three years. Sometimes it does take time because the expectation is big.
"We`ve got to make sure we make a proper fist of it next year.
"But I want to win all six of the games we have left now. I want them to show everyone they can win games and are proud to play for Charlton."
