Guardiola explained his decision by stating that the main reason Grealish did not play in recent matches was because of his own choice, not because of any issues with Grealish's performance. He praised Grealish as a "top player" but also pointed out that other players, such as Doku and Savinho, have been performing well and competing with Grealish for a spot in the team.
Despite his decision to sell Grealish, Guardiola expressed his support for the player and his family. He acknowledged that Grealish is a talented player who has consistently shown his qualities throughout his time at the club. Guardiola even mentioned that Grealish's absence would have made it impossible for the team to achieve their successful treble season.
Guardiola's comments suggest that he is willing to let Grealish go in order to give him the best possible opportunity to move forward, both personally and professionally. However, the exact details of Grealish's future remain uncertain at this time.
It is clear that Guardiola has a great deal of respect for Grealish as a player and as a person. He wishes him well and is confident that he will continue to thrive in his future endeavors.
