Manchester United boss Sir Alex Ferguson says Danny Welbeck is still growing.

Now the Manchester-born striker is fulfilling his potential, even if Ferguson feels there is still a bit of physical development left.

"We were always aware of Danny Welbeck's ability," said the United boss.

"The issue with him now is addressing the physical side.

"When he was 16 he had problems with his knees because he was growing, then he had some thigh problems.

"It was nothing serious, just a matter of waiting for Danny to develop into a man, which we are seeing the signs of now.

"He has a great physique but there is still more to come. Our stats show there's still a bit to do before he becomes a complete adult."
