MistaT these conditions are completely normal, as you mentioned. In another thread I mentioned the following Manchester City injuries: Gvardiol, Kovacic, Grealish, Rodri, Stones, Bobb and others. Manchester City fans have regularly complained about the form and/or wages of various players last year including Grealish, Reijnders, Phillips, Foden and others. All teams have these issues.
I'd rather have problems with Nelson, Vieira, Jesus, Nwaneri etc., knowing that our core team has guys like Rice, Saka, Odegaard, Saliba etc. This is a far cry from the late Wenger/Emery era when the stars were the problems, in guys like Ozil, Luiz, Lacazette, Pepe, Aubameyang etc.
The framing of our challenges often feels like it lacks context/comparables. All problems are big problems when, in relation to what is happening elsewhere, this isn't really the case
