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.
At this point Arsenal's problem is not players because obviously Arsenal has players that can go to any length to play a good match, but their main problem that I’m still trying to know is why Arsenal is not able to keep their consistency till the end of the season to at least secure a trophy. Arsenal can top the table at the start of the season, but when the league starts getting tough, they will start losing points. You are right; there is not a mentality to keep consistency for a long time.
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.
I think even the manager, Arteta, doesn’t really know what to do at this point because I think he is confused, and that is why his team performance always comes down when the season gets tough or maybe the strategy he uses is not the one that will favour them for a long time.
I think Arteta needs to find a possible solution for this team before it is too late. Already they had the same mistake last season, and the season again is about to happen. For almost 3 seasons, the same things have been consistently happening, which is too wrong.
