Pep Guardiola has spoken candidly about the limits of his time at Manchester City, admitting in a new documentary series that nothing in football — or in life — lasts forever.

The Manchester City manager made the remarks in A Beautiful Obsession, a fresh documentary series that follows him behind the scenes and offers a rare glimpse into his thinking on the sport, leadership, and his own future at the club.

In the series, Guardiola reflects on impermanence, acknowledging that "nothing is eternal" — a phrase that has quickly drawn attention from supporters and pundits alike, given how central he has been to Manchester City's dominance over the past decade.

Guardiola has overseen an era of unprecedented success at Manchester City since arriving in 2016, transforming the club into one of Europe's most formidable forces and guiding them to multiple Premier League titles, domestic cups, and a historic UEFA Champions League triumph.

Yet, despite that record, the Spanish manager's words signal a growing awareness — and perhaps acceptance — that his chapter at the Etihad Stadium will eventually close. He has not set a specific timeline, but his openness on the subject marks a notable shift in tone from previous years, when questions about his future were routinely brushed aside.

A Beautiful Obsession promises to offer football fans an intimate portrait of one of the game's most celebrated tacticians at a reflective moment in his career.
