If the outcome of a match was determined only by what you said, then it would be easy for bettors to place bets that hauled in profits. Unfortunately in football, everything doesn't work out the way you think. Even though Real Madrid no longer plays with Benzema, that doesn't mean they will have a much worse performance because a team's performance is not determined only by the role of key players, rather it refers to the strategy and how the players carry out that strategy.
Tactics and strategy are important, if you have the best key players but the strategy and tactics are not good the results will also not be good, Madrid will definitely learn from their mistakes last season when they were humiliated by Manchester City by four goals without reply, clearly that was a mistake in the strategy and tactics applied by Ancelotti where maybe Guardiola can reduce it by using a better strategy than Ancelotti, I think this will be a great match for all of us to watch because two big clubs who were predicted to be champions now meet in the quarter-finals.
I also don't see how the strengths of both of them have talented players or not, it all depends on how they apply the strategies given by the coach to play optimally. This is much more important, so sports betting is full of in-depth research before placing a bet and having a team before the match starts. Madrid against Manchester City will of course be a complicated match to predict, because both have the same strength, even though I prefer support Manchester City but I still have doubts because Madrid could give Manchester City a surprise.
