Striker is no less important but is much better when Arsenal can work together collectively and build a mentality to be better prepared to face pressure until the end of the season. If this can be formed then I am sure Arsenal will definitely reach the desired target in the next season.
If you look at Arsenal's squad, there are very few star players compared to Manchester City or Liverpool. But even then, this team is able to perform brilliantly. The bonding between the players is very strong and Arsenal's match strategy is also good. This is why Arsenal has been able to retain the second place in the table for the last three seasons.
The problem with Arsenal's squad is that although their starting XI is strong, their bench team is not as good as expected. So whenever any important player in the squad gets injured, we see irregular performance from Arsenal. This is the only weakness of Arsenal that we have been seeing for the last 3 seasons. If Arsenal's coach can solve this problem, Arsenal has the ability to dominate the Premier League.
