Sometimes players may not have their day and that is reflected in their playing, but you have to consider that one thing compensates for the other, because how many mistakes can be made up for up front? Many, the most that can happen is that they miss goals, or the worst is that they get sent off. It should also be noted that defense is very necessary because basically Italian football is always based on the best defense in the world, and that is what is sought, by having solidity in defense sometimes you can attack and score goals, that is what is seen in these things, I am one of those who think that when a team has good results they should be praised, and improve on the points that should be done.
Italian football has its greatest art of defense and success of their clubs in Europe and their national team are mainly based on their strong defense. It's their strongest strength but in the past, they had many great attacking players who helped them winning titles.
Recent years, Italy lack of good players in both defense and attacking areas and quality of Serie A and national team fall a lot. Italian clubs must focus and invest more into their academies to get new generations of youth players, who will be foundations for their success in future. They are no longer rich in finance compares to clubs in Spain and England so having good youth academies is only way to succeed and competitive to clubs in La Liga and Premier League.
