It's concerning to see Manchester City heavily dependent on two players for their performance. While every club have an exceptional players, over dependence on a few players can make a team vulnerable, especially if those players are injured. As one of the biggest club in the world, Manchester City should make sure they balance the squad. Football is a team sport, and success comes from collective effort instead of individual brilliance.
But weaknesses that are recognized early will make a team learn and try to fix them immediately. And I think Man City is lucky because with the current decline in performance when their important players are injured, this will make Man City make preparations and improvements as soon as possible. And it is possible that in the next transfer market in the middle of the season we will see Man City buy several players to cover this gap. It would be very fatal if Man City experienced this after mid-season. Because Man City will not have time to make re-preparations such as buying new players unless they wait for the season to end. So yes, weaknesses that are recognized early can be a positive thing for the future because they will be corrected earlier from now on.
