James, who turns 22 today, has made a stunning start to life at Old Trafford.
But he has become an instant target to be kicked from pillar to post by defences — just like superstar Ronaldo — and Giggs said: “Dan takes a lot of knocks but gets up, gets on with it and demands the ball back.
“Ronaldo, especially earlier on in his career, took a lot of knocks and would still demand the ball. It shows huge bravery.
“Dan’s a fantastic character and great professional.”
