It seems so unless Arsenal buy some star players who have a strong mentality to lead the young players in the Arsenal squad, I think Arsenal's problems are always the same towards the end of the season or when fierce competition is happening so we can indeed conclude that this team does not have a strong mentality.
In fact, if we look at the overall performance of the team and also the players that Arsenal have, they have very qualified qualities in all lines, but indeed what happened in Arsenal's defeat last weekend was something beyond technical matters, it will be very difficult to fix.
Besides mentality issues, they also have problems with injured players. there are several factors in my version Arsenal struggle to win trophies, one of which we have mentioned. the factor of several players' substitutes is also important, for example when Odegarrd is injured or not played, Arsenal does not have an equally good substitute to replace him. Arsenal often struggles when playing against mediocre teams that focus on defense, just look at their matches against teams that they should have easily defeated. for example matches against West Ham, Bournemouth, Everton and other matches that ended in a draw. on the other hand, Arsenal is one of the most competitive teams in recent seasons, they often play dynamic modern football. unfortunately, Arsenal does not have a reliable spearhead as a goal machine in their squad. just with G. Jusus and Harvertz is not enough, they often struggle when playing against defensive ones. the role of a pure striker is really needed in matches like this, it's a shame they don't have one. even though if Arsenal had a pure striker, they would have a complete squad. the role of each line will be more effective, and this team will be much more competitive. Well, currently Liverpool can be said to be almost close to the Premier League trophy, in other words Arsenal failed again to realize their target of winning the trophy of this competition.
