For Liverpool supporters I hope they don't have to be disappointed with Darwin Nunez's performance when playing in a friendly match.
True supporters won't be disappointed and they must understand Darwin Nunez's situation. They should know that it is still the beginning of Darwin Nunez's journey in Liverpool. He isn't a robot, he is just a human who needs an adaptation to a new environment. Moreover, pre-season matches aren't really important matches, no problem if he can show his best level.
Maybe in a friendly match Nunez is still trying to adapt to his teammates, because sometimes good players also need time
to find their best performance.
Of course, it is a friendly match, he must try to adapt to his teammates. It is the first time he plays with Liverpool players, so it won't be easy for Darwin Nunez to show his best performance.
We will see the real form of Darwin Nunez when the Premier League has started.
Yes, you are right. It is no problem to perform badly in pre-season matches, he just needs to prove it in EPL matches. I am really sure that he will play better gradually, then he will be familiar with Liverpool's playing style and the characteristics of each his teammate when the EPL match starts.
