Former Derby winger Greg Mills has been told to up his game if he wants to play in the AFC Telford first team again.
Mills has failed to repeat his form after helping Telford to promotion from the Blue Square Bet North last season.
"Greg was fantastic last season, but perhaps the step up has been bigger than he imagined," boss Andy Sinton told BBC Radio Shropshire.
"I'm convinced he'll come again, but actions speak louder than words and that's what I want and need from him."
The 21-year-old had two loan spells at Telford last season, culminating in the Bucks' successful play-off final against Guiseley. He scored three goals in his first six games and ending up with six in all.
He was released by parent club Derby in the summer and had been searching for a deal with a Football League club before agreeing to a 12-month deal back at Telford.
Sinton immediately sent him on a week's intensive training at Lilleshall to get fully fit.
He added: "By his own admission, Greg has been a bit below his best - but it's up to him to show he can bridge the gap between the Blue Square North and the Blue Square Premier."
