"Wayne is fearless and has got a fantastic attitude for a player so young," said van Nistelrooy. "He has great character and has been playing really well. I have been away from United for a long time. But I'm fit again and hungry to play. I can't wait to get back into training and meet up with my team-mates again. I'm ahead of schedule and I've made good progress with my physio in Holland. I could play in the Champions League game against AC Milan next Wednesday."
