In an updated version of the book 'Pep's City: The Making of A Superteam', the writers revealed the turmoil in the relationship between the Portuguese full-back and the Manchester City top brass. The book revealed that Cancelo had threatened to leave the club in 2019 after having just joined the club as he lost his place in the starting lineup to Kyle Walker.
When the pandemic struck in 2020, Juanma Lillo, the assistant manager, was put in charge of trying to convince Cancelo that it was in both his and the team's best interests to put in the effort to raise his game and gain a spot on the squad. At the time, a number of players were sidelined due to injuries, so Pep agreed to give him a go at left-back at Lillo's urging. It was successful, as Cancelo excelled in his new position for two seasons, ranking among the top wing-backs in Europe.
In 2022, however, the relationship turned sour yet again after Cancelo's form hit peaks and troughs at random, causing Guardiola to drop the full-back. The relationship was severed fully when the Catalan dropped Cancelo in the fourth round of the FA Cup against Arsenal. A sullen Cancelo was visibly disengaged throughout Pep’s tactical talk which seemed to be the last straw for Pep who talked to Man City's director of football, Txiki Begiristain and CEO Ferran Soriano as a call to get rid of the Portuguese.
