Arteta mentioned that Saka was running with the ball, wrestling with a defender, and felt a pull in his hamstring. This is a different injury from a previous one he had. The team has already lost several key players, including Kai and Martin, which has put a strain on the team's resources.

As a result, Saka will miss this Sunday's match against Liverpool, a team that has also had a strong start to the season. Losing Saka could be a significant blow to Arsenal's chances of winning the match, which is crucial for their title aspirations.

However, recent reports suggest that Saka's injury is not as severe as initially thought. He and captain Martin Odegaard might return to the team in a matter of weeks rather than months. Arsenal is hoping that Saka will be back in time for their match against Nottingham Forest after the international break.

If Saka is not back by then, his team's title chances might be severely impacted. They will host Manchester City at the Emirates Stadium the week after facing Forest, and Saka's absence could be felt strongly in that match.
