Who would win

I'm some minutes now two big and strong teams that have been winning would have to face themselves

Lyon that sent Manchester City back home last week would versus Bayern Munich that knows how to score most very soon

U never know much about Lyon but I know they sent Juventus which happens to be the champion of Italy back home

This same Lyon sent Manchester City that beat Real Madrid both home and away back to England

I know Bayern Munich that has goal scorers, they don't stop scoring goals until final whistle

One of these two teams (Bayern Munich and Lyon) would have to drop from the champions league this evening

The match would tough so it's not even easy to predict.  So who would win?
