Arsenal only need a striker, the rest of their squad is evenly distributed in all lines so in this transfer market there is no aggressive movement from Arsenal and I understand that.
Arsenal's squad is filled with talented young players in all lines with very even strength so their problem is not with the existing squad, if you look at the last two seasons it's only because of the mentality and front line players that they don't have.
So to cover next season I think Arteta has to find a way to make the team's mentality better and maybe the only thing that needs to be recruited is a front line player who is hungry for goals.
Many have also said that Arsenal's shortcomings last season were strikers. Now they will try to get a striker who is suitable for the competition next season. Their performance was actually very good throughout the season. It's just that they usually have problems near the end of the season and lose points. Several names of players have been rumored with Arsenal, but we will still see what they will get for next season.
