Doncaster's assistant manager Richard O'Kelly saluted striker Billy Sharp, who took his goal tally for the season to 15 in his side's 3-1 win at Derby.
Sharp scored twice and Joseph Mills added a third as injury-hit Doncaster eased their relegation fears with a first win in seven npower Championship games. Paul Green pulled a goal back late on for Derby.
O'Kelly said: "Billy Sharp has scored two goals, but he brings so much more to the environment he's in. He brings an enthusiasm, he brings a desire and he drags others along with him.
"He doesn't take fools gladly, he wants to be successful and people get a buzz off what Billy does. Billy brings more to the table than just goals."
Rovers' defence and goalkeeper Gary Woods were also singled out for special praise by O'Kelly.
O'Kelly added: "The (first) goal gave us a big lift. Derby were the better side in the opening 25 minutes and our goalkeeper has probably pulled off a save that has won us the match and the rest of the defence showed good resilience during that time. The goal certainly gave us a lift."
