Saka limped off during Arsenal's 5-0 win over Leeds United, and Arteta said that he is trying to get back to full fitness as quickly as possible, but they need to respect the recovery process.

Centre back William Saliba, who has been sidelined with an ankle injury, trained with the team today and may return to action soon. Arteta said that they have a decision to make on whether to play him or not.

When asked if Saka was also ruled out of upcoming games against Athletic Bilbao and Manchester City, Arteta said that he is not yet ready to return to action.

Arteta also provided an update on the progress of other injured players, including Kai Havertz, who is recovering from a knee injury, and Gabriel Jesus, who will not return from his ACL injury until December or January.

New recruit Piero Hincapie could make his debut for Arsenal, but Arteta said that they will be mindful of his recent travel with the Ecuador national team and his limited training with the team so far.

Arsenal face a Forest side that has a new coach in Ange Postecoglou, who Arteta praised for his clear style of play and ability to get the best out of his players.
