Wright-Phillips was recalled to the starting line-up for draw against Aston Villa and produced a far better display than many previously seen in a QPR shirt.
"I think confidence is the key for him," Redknapp said. "He has to play with confidence.
"He made some good runs and great ones in the first half, where he should have scored and then hit the post.
"But he bent his runs in off the line and looked lively. He has done well in training and I gave him a chance."
