Speaking on ESPN FC, former Chelsea midfielder Craig Burley said: "Arsenal have started this season with 10 players. There is no difference between a red shirt and a blue shirt in Kai Havertz's performances.
"If Manchester City keep winning, and more pressure gets on Arsenal, this elephant in the room won't go away until Mikel Arteta does something. He might say that if they're winning games they'll carry on."
"But they can't carry on with a guy who is short in confidence, not a goalscorer, giving the ball away, hiding in games, doesn't want the ball. I believe this is a huge problem for Arsenal if they're going to keep up with Man City."
Arteta has included Havertz in the starting XI for the first four games of the new Premier League season despite the German's lack of impact on the pitch.
It remains to be seen whether the situation will change after the international break but it's clear that the Gunners can't afford to have a passenger in the team.
