If you look at Real Madrid's pre-season fixtures, they will face AC Milan in the near future, interestingly Real Madrid will face many big clubs in their pre-season matches. I want to see how they do in the pre-season matches, I won't judge them and conclude, but I will see the development they will show during the pre-season matches. There will always be a difference between pre-season matches and real matches, but it can be a reference even if it doesn't guarantee it.
We'll be shown some matches from big clubs as they prepare.
