Derby County boss Billy Davies says new signing Kenny Miller can bring out the best in Robert Earnshaw.
"I have got some new players. I have seen Eddie Lewis in one game, we've been missing Benny Feilhaber because of injury and the same applies to Kenny Miller.
"We have not actually got these guys fully fit and playing together. Once we get everybody fit and find a certain team, I am very confident we will go from strength to strength.
"We have got to give players time to adjust to the new environment."
