Nigel Clough feels Blades fans are starting to see leading scorer Marc McNulty find his best form.
The 22-year-old, who has netted in both of United's wins of 2015, earnt praise from his manager following his goal in Saturday's win over Preston North End at Bramall Lane.
Speaking in the aftermath of the weekend's 2-1 win, Clough remarked: "It was a mature performance from Marc and you can certainly see a massive improvement in him from when he first arrived.
"He is working harder than he ever as done, he is looking fit and strong and he is holding the ball up. He is now resisting more challenges from the defenders which enables him to bring our midfielders into play."
The Gaffer is now for looking for the Scottish marksman to produce the goods on a regular basis as the next stage in his development.
Clough added: "We have worked tremendously hard with Marc throughout his time here and we are now seeing the rewards, but as we have told him he has now set his standard, what he must do now is perform with consistency
"He has scored ten goals already and he always looks like getting a goal when he is on the pitch, but there is still room for improvement and more to come."
