Guardiola will next season manage City having signed for the Premier League club after three years at Bayern Munich.
His duties at City were however out of his mind as he let his hair down at Ibiza alongside his wife Cristina Serra and their three children Marius, Maria and Valentina.
The coach and his family are pictured enjoying themselves on a yacht off the Mediterranean Island.
Guardiola is due to be officially unveiled in Manchester on July 3 but he has already kicked off work as manager.
He has made £21m signing of Ilkay Gundogan from Bourssia Dortmund and Colombian wonderkid Marlos Moreno is also set to sign.
City have also been linked with the likes of Everton defender, John Stones, Dortmund's Pierre-Emerick Aubameyang and Dinamo Zagreb's Ante Coric.
