Yes you are right. If a team is not mentally strong then they cannot do much good on the field of play. Because the mental strength of a person takes them a long way. If he accepts defeat in advance that he or they cannot do it then they will never be able to win.
If Arsenal does not learn from their previous mistakes then it will be their big mistake. Because mistakes can be made but we have to learn from those mistakes. If Arsenal cannot understand their mistakes this time and if they make the same mistakes like last time then maybe Arsenal will not be able to win
Arsenal’s main weakness is that they go through a slump every season, which stops them from staying on par with the league leaders. I don’t know if you can really call it a mistake, it’s the result of their overall performance, so if there are any mistakes, they probably come from the coaching staff. Most likely, the training process is set up in a way that at some point the players struggle to handle the physical load, and that’s when the slumps happen. Or maybe it’s more about emotional fatigue. In any case, Arsenal is a good team and statistically very strong, but for some reason, they always seem to hit a slump in the middle of the season.
