Arsenal must be very frustrated to lose their Champions League chance by their poor performance on the final weeks of the season. Tottenham also deserved to qualify for it of course but Arsenal were doing a better job for them for some time actually. However they couldn't maintain this form on the most critical weeks. They really need to strengthen the lineup now to play bigger next season. They have a potential and they can bring it out by signing a good centre-forward.
The problem that exists with Arsenal from time to time is only one, namely the player's lack of a winning mentality. Arsenal is recognized as a club that always produces young players with extraordinary talent but always fails to win the title.
Ozil and Fabregas who had a winning mentality but they also left. The arrival of Aubameyang from Borussia Dortmund brought a bit of good color to Arsenal because he was a player who had a winning mentality before moving to Barcelona.
The average players currently owned by Arsenal do not have a winning mentality. Arsenal's young talents are only able to provide an interesting spectacle through beautiful games, but that is not enough because the ultimate target of a club is to win in domestic leagues and European competitions.
Arsenal must look for strikers, midfielders and center defenders who have a winning mentality to face next season. Don't just be in the attacking position because it will have no effect or be unbalanced for a team.
