I felt bad to see Saka leave the field yesterday, but I'm sure it’s just a minor injury, and he will be back after the international break. Saka has a great impact in Arsenal, and whenever he is injured, then Arsenal performance is going to drop drastically, but from what happened yesterday, it’s obvious that it’s a minor injury, and we expect him to be back soon.
Since Euro 2020 but hosted in 2021 year because of Covid-19, Saka was over used by both Arsenal and England national team. He started to get his first injury since 2020 in the last season and after that injury, he began more sensitive with injuries. I believe that these injuries mainly come from his exhausted body and Arsenal must see it seriously.
They need Saka because he is one of their most important players, but to get most contributions from Saka, they need to protect him and protection means using him properly and giving enough time to rest and recharge energy for his body. If Arsenal continue to overuse Saka after this injury, things will become worse.
