Abeg o, liverpool & van dirk are not the only one to suffer major injuries this season. Infact mancity have suffer more injuries to key players than liverpool. These are lists of mancity player with injuries this season:
Aguero, debruyne, gundogan, bernado silva, gabriel jesus, ferran torres, fernandihno, rodri, walker, laporte, ake, mendy, dias, ederson.
Mancity have suffer more injuries than any other team in epl & yet they still manage to move on.

So liverpool, keep quiet, stop complaining & move on.

Even last season that the entire mancity defensive line was completely injured such that fernandihno and rodri were used as central defenders, mancity stil manage to finish second on the epl table.

Even in 2018/2019 session that mancity won epl with 98 points, debruyne, kompany and aguero were missing for almost throughout the season.

So stop complaining liverpool.
You are even lucky that your front 3 of mane, salah & firminho are stil fit after 3 yrs,. What of mancity that cannot boost of that?

Welcome big man
