Big-bodied youngster Charlie Constable has impressed in his first four weeks back at pre-season training.

"His ability to win the ball and distribute to his teammates with a beautiful handball is a skill that I think is underrated in the modern game," Cats assistant coach Matthew Knights said.

"I think that's one of Charlie's big parts of his game and also his kicking is very precise. Ninety per cent of the time if he's got the ball, he's going to find a target with his kicking.

"He's still got to work for it and show that he's capable at AFL level but he's showing good signs at the moment."
