Yes, hopefully Arsenal can still maintain their performance because after all, I think all teams will always have the same risk for their key players getting injured. But indeed, the injury to Gabriel Jesus will greatly impact Arsenal's position at the top of the Premier League standings at this time.
But of course this incident can also be a valuable lesson for Arteta, because when a key player is injured, of course Arteta is required to make even more difficult rotations.
At least Arteta should be able to maintain good results until the end of the year, because after the World Cup the reality is that the English Premier League will restart which means they will restart before the transfer window opens.
Therefore, Arteta must be able to have the best way to be able to maintain Arsenal's performance at least until the end of the year. Because after that Arteta can make purchases of players, which are at least enough to replace or be able to strengthen their attack line due to the temporary absence of Gabriel Jesus.
So far Gabriel Jesus has been a very important player in the Arsenal team and Arsenal's excellent game so far, of course, has a very large share of Gabriel Jesus and with the absence of Gabriel Jesus of course it will greatly affect Arsenal's performance.
however it all comes back to Arsenal coach Mikel Arteta how to handle this.
and so far due to the world cup we can see players who have improved performance and also injured players, it will all have an impact when they return to their respective clubs, be it positive or negative changes.
