Mikel Arteta's praise for Kai Havertz's performance suggests that the German midfielder's chemistry with other players is a key factor in the team's success. Arteta stated that the chemistry between Havertz and Martin Odegaard and Bukayo Saka is "fantastic" and that Havertz's enjoyment of the game is a major contributor to his success.
Jamie Carragher's comments on Sky Sports also highlight Havertz's importance to the team, saying that "you need to be one of the best players in the world to replace him". This suggests that Havertz's impact on the team is significant and that replacing him would be a difficult task.
Arsenal's next match is against Manchester City, a tough test for the team's strength and depth.
