Pep Guardiola will miss Manchester City's next two matches after a "routine operation" on his back Tuesday, the Premier League champions announced.

City said their treble-winning manager had been suffering from "severe back pain for some time" and flew out to Barcelona for "emergency" yet "routine" surgery.

The Spanish boss will remain in Barcelona while he recovers from the operation and is expected to miss City's matches against Sheffield United this Sunday and Fulham on September 2, with assistant manager Juanma Lillo taking temporary charge in his absence.
