It remains unclear just how players and clubs will react once domestic football returns after the World Cup but the worst fear was always obvious. Injuries.
Injuries are an inherent risk in any international break but they have become amplified due to the tournament coming in the middle of the season and its truncated nature giving players even less time to recover after every match. Fatigue is inevitable and that only increases the likelihood of injuries, especially in such intense matches.
Manchester City have the vast majority of their senior squad out in Qatar representing their nations but *touch wood* they have been fortunate so far on that front. None of their 16 players have picked up an injury as of yet, in fact, Kyle Walker has actually returned to action following his time on the sidelines due to a groin problem. The same can't be said for Arsenal.
