The Dutch striker left United for Real Madrid in the summer of 2006 after falling out with Sir Alex.
Van Nistelrooy told the Sunday Mirror: “I’m so looking forward to seeing him again. I want to talk and make up, clear the air between us.
“After all this time I can’t believe or understand what it was really all about. Why did it have to be such a big thing?
“I think we were both to blame. It just exploded between us.
“Because we had such a smashing relationship, I just though, ‘What on earth are you doing to me?’
“I was so upset. As a professional player you never get so attached to our club or manager that a clash will hurt you that much.
“But in this case it did. It got very personal.”
