Nah, its just a similar piece of music, because they are similar scenarios. One is crowning the champions of europe, the other is crowning a king. If they wanted to make the lol moment they would have just bought the piece of champs league music and used it, its a pretty commonly used piece of music so wouldnt be expensive.
I still think it would have been far better to have the coronation song being "We are the Champions" because that would have been even more amusing, but they sadly decided to take the serious approach. Its a good bit of score though.
