The moment features in the four-part series "A Beautiful Obsession," which begins on Amazon's Prime Video this week and follows Guardiola's final two seasons in charge at the Etihad.
The scene comes after a 2-0 Champions League defeat to Juventus in December 2024, with Guardiola opening up to his squad about his separation from wife Cristina Serra.
"Guys – I want to confess something," he tells them. "I'm f***ing divorced from the most beautiful woman on your planet. It's my wife – my ex-wife. I love her unbelievably. But we lost the passion. For many reasons, we lost the passion. I love her absolutely. She loves me, yeah, but we lost the passion.
"And it's how you play football. You play because of something inside — but where is the passion? In your life whatever you are going to do, do it with passion. I don't want good players, I want players with passion."
Guardiola and Serra had been married for ten years at the time of their split, with news of the separation first reported in Spanish newspapers in January 2025. Serra moved to Manchester with the couple's three children when Guardiola took over at City in 2016, but cracks began to show in 2019 when she returned to Barcelona, leaving Guardiola alone in a city-centre apartment. She is understood to have been further frustrated when Guardiola appeared to renege on plans to leave Manchester City and instead signed a contract extension in November 2024.
The documentary shows Guardiola returning to the subject nearly a year later, after a 2-0 home defeat to Bayer Leverkusen in November 2025.
"I leave my life, my divorce, my family is away — and everything for all of you," he tells his players. "And what do you give back. The f***ing performance you've just done — all of you. It's a disgrace, guys, and you know what's going to happen. You will have another manager."
Manuel Estiarte, City's director of first team operations and a longtime confidant of Guardiola, says in the documentary that it was important for the squad to understand what their manager was going through at the time.
"I said to the team, 'Please, you have to understand. You're not playing with a coach who can be a bit impulsive, who can be a bit intense. Who can sometimes be a bit up and down. You're seeing a human being. He's getting a divorce. This is a topic I don't want to talk about too much because it's personal. But it was necessary for the team not only to visualise Pep as a manager but for the first time to see Pep as a human being."
Asked in a separate interview featured in the documentary whether he considered himself a happy man, Guardiola reflected on the broader changes in his life.
"In my life I've made a lot of changes lately, right? So I've got divorced and I have to settle a bit." Asked directly if he was happy, he replied: "In my job, yeah."
Guardiola, who left his role as City manager at the end of last season after ten years in charge, is said by those close to him to remain hopeful that he and Serra could yet reconcile.
