We're yet to see the very best performance from these elite teams. The UEFA bodies should make some impacting changes because coming with this current ones, I don't think it will make any difference especially for the elite teams that qualify for all tournaments. They're anticipating in every tournament, divided focus and the least the UEFA body can do is simply instruct a new standard, inother to make things go easy for these clubs. Real Madrid players get exhausted because they play more games and not given enough resting time. These players are not bots but human beings that trained to stay fit.
Don't worry, the season hasn't started yet even though there is already a club world cup as a diversion but that is not a benchmark because for now the club is still trying apart from making the current squad better they are also still looking for players needed for the club next season so that in the end there is no need to feel that they are not developing or have not improved themselves because the season has not even started.
Now the club world cup or even the friendly matches that will start soon are still a trial to see the club's early development for the deep season so that in the end we still can't talk much about the appearance because after all we must be aware that it is still too early for that.
Currently several big clubs are starting to make moves to make their squads better and we just need to see how far they are ready in recruiting players this time.
