Something is wrong with you and you are taking all of those things out of context. The Del Piero thing was a joke, I read the whole Italian interview myself. He jokingly said those things and then ended it all by explaining that they don't have that kind of relationship outside of football.
The Milan thing was something that everybody was saying at that time. Us fans believed Milan would win, experts did, our players did.. They were big favorites back then. Us winning this year with those players was a surprise to many.
And lastly, the whole him celebrating against us never happened. He scored plenty of goals against us and had the chance to celebrate many times but never did.
