Only the stamina factor must be observed for next season because Arsenal is always hampered by stamina, they lose moments when playing important matches to get points, but Arsenal lose because of that, Arsenal always lose their style of play at the end of the season, Mikel Arteta just needs to improve his stamina. players and sharpen each line so that next season they will be able to win the championship title which has been won by Man City for the past two years.
If you look at it as a whole, the performance of the Arsenal players is actually quite good. It has been proven that in these two seasons, Arsenal has always been a tough competitor to Manchester City and Liverpool for the top position in the Premier League. In fact, Arsenal always almost won the Premier League in the last two seasons, but unfortunately this didn't happen because Arsenal always experienced a decline in performance towards the end of the season. That's why Arsenal always fails to win the Premier League.
Maybe what you say is true, that Arsenal players still have problems in terms of stamina. However, in my personal opinion, it was not only stamina that was the main cause of Arsenal experiencing a decline in performance at the end of the season, but also mental factors and lack of concentration. The reason is, at the end of the season it was seen that Arsenal players were unable to play as freely and calmly as they did at the beginning to the middle of the season. And because of that, I concluded that the main factor influencing the decline in Arsenal players' performance was because their mentality and focus were slightly disturbed.
Because if you look at the stamina of the Arsenal players, in my opinion there was no significant decline from the start to the end of the season. So next season, in my opinion, Arteta must train his players' mentality and self-confidence so they can be better. So that the players can continue to maintain consistent performance throughout the season and continue to be focused. Because in terms of skill, I think Arsenal's current players are quite capable.
