Mikel Arteta have alot of work to handle, he looked more worried about his key player who's under probability of starting against Manchester City.
Yeah it's a real issue when a player gets injured but we do have options like Rowe, Havertz, Nelson, Trossard who can do well playing at that position. It's about adaptability and Arteta needs to assess that before selecting the replacing player for Saka in the lineup. I think Arteta is not worried about Saka injured for City game but he is more worried about how long it will take for Saka to be back again.
Mikel Arteta would sort out replacements for his winger and probably suits in the best strategy against Pep Guardiola men.
It's a tough decision to make but I feel Arteta has lot of options. Like I said, he has to assess a lot before making the right one that he feels but we really can't afford to lose this match or share a point against City. We need to win in order to be ahead of City.
