Ferguson says Jones is an "animal for football".
He told Inside United: "Jones is going to be a fantastic player, his talent is unbelievable. Yes [his best position is centre-back] but you could play him anywhere. I think you could play him centre-forward! He's just that type of player, he's an animal for football. He grasps the game, he understands it. Play him right-back? Brilliant. Play him centre-midfield? No problem. Play him centre-back? Terrific.
"He's just one of those unusual players you get now and again who can play anywhere. We've not had a player like him in terms of someone who can play at that performance level since, well the closest you would get would be Brian McClair.
"Now, Brian McClair was a fantastic player. He could play anywhere, McClair. I remember kidding him on once; I said to him, just go and play in the right-back area and he laughed. I said to him, 'What are you laughing at?' and he said, 'Next week I'll be centre-half.' But that was his character, so composed about life. Nothing bothered him."
