Many players left City already and Pep's decision and signings during this transfer window will go a long way to decide the fate of the mystery blue this season. It not just about strategy but having the right team that matches the strategy and can also deliver the expected outcome of the strategy. Let's see the outcome of the transfer market then it will much easier to decide what the season will be like for them.
Pep did some good signing during the transfer window which is impacting the team both in their form and strength of which Pep is still trying to manage as much as he can to get the results which is desired of the team and I agree that getting the right team to fit in the strategy of the team is key. Like you said which I agree, strategy is not all that is needed at all the time because even a good strategy will work if there are people who will carry it out and ensure that it produces the desired results in the end.
