Derby County boss Billy Davies is confident Robert Earnshaw will prove his worth.

He said: "What I saw after the Reading game was a player who was all of a sudden finding his feet. He came on and looked more like the Robert Earnshaw that we know.

"I've got to have patience with some of these players. They come to a new club, I've seen it before, you've got to be patient and supportive.

"You've got to give them time to adjust and some do it quicker than others. The one thing they do get is maximum support from me and the staff because we know they are going to come good."
