I remember Arsenal get their best playing style for several months when they make a jump from degradation to top 6
Then slowly they lost cohesiveness the coach needs to get that moment back and repeat it again
For next season it seems that bad things will not happen again to Arsenal, because the arrival of a very talented new player will make all lines become more compact and Arsenal will definitely be able to compete with all the great clubs in the Premier League. Are you unsure about the potential and experience of the coach at Arsenal for next season?
Arteta already has a good experience with Arsenal and last season did well despite failing to make it to the champions league, but they have evaluated everything Gabriel Jesus and Rafinha will be brought to Arsenal to strengthen their attacking line they are sure that next season will be tough competition but Arsenal can overcome it all from its previous slump.
And some of the signings were clear they wanted to be stronger because Arsenal didn't want to be derailed last season.
