Actually, for the semi-finals, I also feel that whoever wins, whether it's Madrid or City, they will be the champions now.
I think you just woke up from a dip sleep mate, because the championship semi-finals between Real Madrid vs Manchester City were played over 30+ hours ago and you are still talking about the possible winner to be the winner of this year's trophy, well for your update, Manchester City won Real Madrid with a whooping 3:0.
So can we now conclude that Manchester City is already the winner of this season's championship?
