It's easy to predict, the winner is Manchester City.
Real Madrid was struggle to beat Leipzig, Leipzig isn't really a strong team. But Real Madrid beat them with small margin, unlike Manchester City which destroy Copenhagen in both match.
First leg, Manchester City will win, so it's good to make a bet.
But for the second leg, Manchester City might not use all of their strength because they want to secure the points.
Our predictions this time are different, sorry. I believe the winner is Real Madrid because Real Madrid has changed a lot this season and their strength is even stronger than last season. You don't need to doubt Real Madrid's mentality to take revenge last season.
Maybe I also want to tell you that you completely forgot that Brahim, Joselu and Bellingham replaced Mariano, Hazard and Asensio. Additionally, players like Vini, Valverde, Camavinga and Tchouameni have been better players this season. Moreover, Man City have not performed well this season, they also lost Gundogan in the midfield which reduces the way they dictate the game, if they were spectacular they should be at the top of the EPL right now. this is just logic.
