Managers try different stuff now and then. Sometimes it works (our performance v. Chelsea on our first season back on the EPL for example) and sometimes it doesn't.
It's not an outrage, it is what it is. Nuno's trying to shift the "counter-attack" mentality and play style we had these last seasons. It works sometimes, but we were shown that it can be broken apart by the right choices, as the results after the COVID break can demonstrate. Something is not working right now, and I fully believe Nuno can, and will, fix it. But it is not an outrage.
