The American has enjoyed playing alongside England's record goalscorer at Pride Park, and claims his "quality comes out every day"
Duane Holmes has praised Wayne Rooney for helping him to improve his all-around game at Derby County, labelling the veteran midfielder a natural "winner".
Rooney officially joined the Rams on January 1, having agreed on a move to Pride Park last summer while on the books of MLS outfit DC United.
The 34-year-old has since appeared in five Championship matches, contributing two goals and two assists to help Phillip Cocu's side start to climb away from the bottom of the table.
