Watch RSC Anderlecht vs Athletic de Bilbao Live StreamingEngland international Downing was on target twice in Aston Villa's 5-2 romp against Burnley at Villa Park on Sunday.
He had only scored once in his previous 19 games before that brace and had gone 16 matches without a goal.
Now he has ended that drought, O'Neill hopes he can finish the season with a flourish - starting against Palace.
O'Neill said: "His confidence has been boosted with his two goals against Burnley.
"I think he has been doing very well for us without getting the occasional goal.
"That is the part of his game which he feels he can improve upon as he has a really good shot and I think his two goals against Burnley will have lifted him enormously.
"He is a confidence player and you can see the ability he has.
