It seems you have forgotten so quickly, Real Madrid played the FIFA Club World Cup, Barcelona did not. All that time they have been resting so it's quite understandable that they have started their friendlier earlier than Real Madrid who are also probably resting for some time. So no, as of now, he is not clueless or making players lazy.
I think Xabi needs time, I don't think it should be fair to criticize him based on that bad performance vs PSG
Yes, perhaps Real Madrid are currently in a resting phase, because as you said, Real Madrid have just finished the world cup competition they participated in. That's why it's only natural that Real Madrid haven't had a trial match with any team at the moment. But even so I don't think it's appropriate to say that Real Madrid players are lazy. Because in essence they also need rest and also need a vacation with the people they love. So with this, I think it's only natural that Real Madrid don't have a trial match at this time. Because as far as I know there is no schedule for Real Madrid to play with any team at this time.

In addition, last night Barcelona won the match against Vissel with a score of 1-3. In that match Barcelona fielded many new players and their second-tier players. Rasphord also played in this match, and he also had a pretty good performance in this match. Although he couldn't score, I saw Rasphord had a pretty good contribution in this match. Maybe with a few more adjustments Rashford can play even better in Barcelona. And in a few days Barcelona have another friendly match scheduled against FC Seoul. I think Rasphord should make good use of this match, if he wants to be seen more by Hansi Flick.
