I had a cut knee once and I had to have a crazy bandage on what was pretty much a 3cm wide cut as it was right in the knee.
Took about 8-10 days to be able to reduce that so makes sense he is out of the international games. I would say possible for Man City.
It’s a difficult place to heal and runs a pretty high risk of infection. I once missed about 2 weeks with an infection that sprung up during the course of a single training session and resulted in my foot swelling to the point we had to cut my boots off.
Yup it’s a wait and see with that type only positive is it’s 2 and half weeks and it’s an injury that has no additional issues bar the healing.
