Charlton boss Powell admits interest for Palace's Williams
Powell believes Williams could help reverse his side's flagging fortunes.
Powell said of the 20-year-old: "He's a good, lively, exciting player. We do need players of that quality coming in.
"He's possibly available after Saturday's game. Whether that happens or whether there's a queue of clubs in for him I don't know.
"He's someone who I've seen over the past year or two and who I feel if he ever came to us would improve us."
