He said: “He was excellent, absolutely excellent when he was on the field.
“He was so good. His movement inside the box was great. He was nearly always lurking at the far post, Lee Gregory took the front post and he was at the back post, but he was moving a lot and then when [Tom] Lawrence was drifting at the far post Waghorn would dart across his defender, his movement was so good.
“His work-rate, I never question how work-rate, his work-rate is always good and he was a problem.
“He was a problem out there, he was pressing really well, he was starting to press really well, chasing defenders down and then bang, just like that when he is chasing a defender down, really tried to make his impression on the game, he does his hamstring in and we hope it’s not serious.
“He will almost certainly not play on Monday.”
Derby signed Waghorn back in the 2018 summer transfer window from Ipswich Town for a fee of £5.04 million.
Since then, the 31-year-old, who is currently valued at £1.8 million, has made a total of 119 appearances for Wayne Rooney’s side in which he has managed to score 28 goals and provide 12 assists along the way (per Transfermarkt).
Do you think Waghorn was Derby's best player against Luton?
TIF Thoughts on Ryan Conway’s comments on Waghorn…
Despite only playing in the first half of the game against Luton, Waghorn still managed to pick up an assist and earn himself a decent match rating of 7.31/10, making him Derby’s fifth-highest-rated player on the day, which just goes to show why Conway was so delighted with his performance.
Moving forward, everyone at Derby will undoubtedly be hoping that Waghorn’s injury will not keep him out of action for a significant amount of time considering how many games Derby have left to play this season and the fact that they are only eight points ahead of the relegation zone.
