The two goals scored by Madrid in that match were actually not due to the greatness of the Madrid players, but rather the poor and weak defense that Chelsea currently has, even from what we saw today, don't we all really miss Rudiger, Thiago Silva and also Koulibally is currently in Chelsea defense, not the clowns that Chelsea bought expensively, such as Fofana, Colwill and Badiashile.
I think Madrid second goal could have been prevented if only Badiashile had moved quicker to block the ball into the goal and not just watched without making the slightest effort to prevent it.
The 2 goals Madrid scored came from 2 failed offside traps from Chelsea which Madrid made good use of. There were a lot of mistakes, especially in terms of communication and relying too much on each other, which made Chelsea hassle themselves in securing their defense.
Madrid's attack pattern is still not too good actually and we can see that there are so many opportunities that seem to be wasted by Madrid but on the other hand it cannot be denied that although Madrid is still not too good in terms of attack but Chelsea is also very bad in their defense which makes Madrid win and seems to be an easy match in this match. Enzo Marescca still has to work hard to change Chelsea at this time because they still have not shown the performance they should show.
Losing or winning is not an important result in a friendly match like this because the most important thing, of course, is that the coach can evaluate to be able to improve the team's performance to be better for next season. So yes, I personally will not blame them as you said and also cannot want the old players you mentioned to return. Because anyway, with a friendly match like this will also certainly make the coach be able to correct his shortcomings and mistakes.
But, if Enzo Maresca is unable to improve the team's performance next season, then of course Chelsea will again fire the coach at the end of the season. Because after all, a coach must certainly be able to make the team better after doing a lot of strategy experiments also in pre-season matches like this. So yes, let's just look forward to whether Enzo Maresca will succeed in making Chelsea better next season or not, or maybe for the umpteenth time Chelsea will fire the coach. Lol
