Manchester United manager Sir Alex Ferguson wants David de Gea to develop his slight frame in the gym so he can become a top-class goalkeeper.
The Scottish tactician is a big fan of the 21-year old Spaniard but is well aware that he needs to add some muscle to his body before he can really mix it with the big boys.
"It's a matter of developing his frame. He's doing a lot of work in the gym.
"If we can get maybe a stone on him without losing any of his flexibility or speed it would be a great boost to him.""The boy has got talent. He's lightning quick but has just found it difficult to adjust to some parts of the game here," said Ferguson.
