Some of it is probably due to the amount of games, as you said. But players like Nkunku and Lavia were out before the season even started, made an appearance and couldn't even play the full 90 before they got injured again. James couldn't finish the season opener and after missing months made a brief appearance and is out again. Chilwell is in and out constantly, Fofana hasn't had a consistent run of games since his Leicester injury, Chukwuemeka has barely played and has been out forever. We used to play in the CL every season, now we don't and yet we somehow are debilitated by long term injuries that players don't seem to be able to recover from. Something's not right.
