Havertz, 26, has been out of action since then, and Arteta initially expected him to return at the end of November.
However, the manager has now expressed optimism that Havertz may be able to return to the pitch in a shorter timeframe, saying he could be back in "weeks" rather than "months".
When asked about Havertz's recovery, Arteta noted that the player's progress is positive and that he is being carefully managed to ensure his knee heals properly.
Arteta emphasized the importance of allowing Havertz to make a full recovery, stating that the team misses him and hopes he will return to full fitness for the long term.
