I think the problem with Man City and the mistake made by Pep Gourdiola was building the team solely on Kevin DeBruyne as the only playmaker and the consequences of his injury had affected the team such that the team became very inconsistent this season, the team shouldn't be build on a single player meanwhile the exit of some of their key players such as Gundogan and Mahrez did also affected the team while their replacement didn't live up to expectations and Pep Gourdiola being a competent manager thinks he knows all and has the wherewithal to win any trophy with any player or squad had now fall short of many their supporters expectations.
I don't think it's a mistake; it's a double-edged sword—use it skillfully, and it works; use it poorly, and it backfires. Any playing style has its strengths and weaknesses, and its effectiveness depends on an individual. Here are some advantages:
High Effectiveness: A superb player can utilize special skills and talents to create goal-scoring opportunities or change the game's dynamics.
Creating a Difference: Superstar players have the ability to make a difference in any situation, solving problems, and creating goal-scoring chances even when the team is struggling.
Team Spirit: The excellence of a player can boost team morale. Teammates often feel more confident knowing they have an ally capable of making a difference.
However, it also has its weaknesses:
Lack of Diversity and Predictability: If a team focuses solely on one player, they can become predictable and easy to anticipate. This reduces the team's ability to change tactics or adapt during a match.
Injury Risk: If a key player is injured, the team may struggle to find a suitable replacement. Depending too much on one player can create a boundary and risk for the team.
Pressure Burden: Key players often face significant pressure from both the team and fans. This psychological burden can impact performance.
Looking at Mancity's dependency on players like Kevin De Bruyne and later Rodri, they faced difficulties when these players were suspended and injured. However, Mancity's squad quality is high, especially with Pep's unique tactical rotations. When Pep chooses this playing style, he has specific calculations. I think this period is just a challenging moment for them.
