Bartomeu did a sort of economic sabotage, which is a tempting trap to fall into. He's spent so much with so little care about medium-long term economic stability, that he banked on future revenue to finance some of the deals he made.
It's as if you win 2000 euros a month, but you make deals in the resent projecting on that you'll make 2500 euros a month in the next year or so. All of this based on the mirage of ultra-high revenue booming. Now imagine you not only don't meet the expected gain, but you actually decline from 2000 euros/month to 1000 euros/month (covid crisis role). All the while contracts are signed pen to paper and binding by nature.
This is the problem Laporta inherited from the previous board. He simply inherited contracts made on the basis of economic growth that he has to pay up in economic recession instead. Impossibly hard to deal with.
Which is why people need to cut him some slack.
