Yesterday I saw the preview of the Juventus match against Borussia Dortmund and I have to say that the team's performance really surprised me, I have to say that these guys are serious, if that is a pressure of the season preview they are really strong
Being strong alone is not the key to winning the league. You will see teams that initially seem strong at the beginning of the season, and then see them start to decline in the middle, and even worse at the end of the season.
Pre-season matches are important for allowing newly recruited players to adapt to their team. Although I am sure they are not showcasing their true strength, I believe some players are showing their best to gain recognition from the coach that they are ready to be part of the main squad.
