Midfielder Young urges patience from Aberdeen fans
Young knows supporters may have been alarmed at the sight of regulars - such as Barry Nicholson, Steve Lovell and Jackie McNamara - quitting the Dons but the midfielder has backed Calderwood fill the void left in the dressing room.
Speaking on RedTV, he said: "You get a bit wary when you see that many boys leaving but we have been doing a lot of training and running and the boys are looking really good.
"The young boys who have come into the team are showing fantastic ability. The new signings are a boost and I think it's looking well for next season.
"The manager has shown that he's not going to buy just anybody for the sake of it, he is looking for quality players, and I think the fans will be happy with the signings we have made so far.
"They are maybe a wee bit frustrated there are not more in at the moment but it's a long summer. You see how it happens in England too, scrambling right up until the last minute.
"The boys in the changing room aren't daft - we know the manager will get players in.
"From the fans' point of view, they maybe want everything a bit too quickly but hopefully there will be quality signings coming in.
"I've got no doubts about that."
