Guardiola's departure has now been announced, with Enzo Maresca his chosen successor.
The change in leadership has reportedly unsettled parts of the squad, with senior players now reassessing their long-term futures at the Etihad.
Haaland, 25, signed a long-term contract extension until 2034 just 18 months ago, but his commitment is now being viewed through a new lens.
Although the Norway international remains settled in Manchester and has no intention of leaving this summer, his future beyond 2027 is now reportedly less certain.
According to Mundo Deportivo, Haaland is expected to evaluate how City’s new project develops before making any long-term decisions.
The striker is said to be open to reassessing his position if the club’s sporting direction shifts significantly without Guardiola.
For now, Haaland remains focused on performance after another strong season in front of goal.
However, his comments at the end of the campaign reflected frustration, as he urged City to respond strongly after falling short in the Premier League title race.
Manchester City’s hierarchy now face the challenge of maintaining stability during a major managerial transition while also protecting the long-term future of their most important players.
The post-Guardiola era is already beginning to reshape expectations around the squad’s structure and ambitions.
