For Arsenal it's a tough test. Last season they haven't felt a moment like this one. Under the circumstances of a busy schedule in some competitions. So there should be an adjustment, and that has passed Arsenal in a few seasons. So Arteta must be ready to rotate players. Maybe he will fight a lot of fatigue and injury. But perhaps the selection of young players is part of the strategy for this season. With this strategy, maybe their stamina and strength are still good enough to fight with a busy schedule.
Arsenal should learn from previous experience where maybe their players are tired and maybe injured more easily so that at the end of the season it looks inconsistent so the chance to become the EPL champion failed after Manchester City overtook them, this season even Arsenal has two focuses apart from their domestic league they also started to focus on the UCL it is clear that players will tire easily if they divide the two focuses.
Arsenal really need to take in new players like young players which has been done by many clubs including Madrid to recruit young players to be able to focus on the UCL and the domestic league with young players obviously will not experience player fatigue especially of course performance will remain stable and stamina will also be maintained. there is a lot that arteta has to overhaul again, considering that the pre-season match yesterday lost against Manchester United.
