Pep Guardiola is set for a spell away from Manchester City after undergoing back surgery, the club have confirmed.
He will be replaced on the touchline by assistant, Juanma Lillo, until he returns after September's international break.
A statement issued by City on Tuesday read: "Pep Guardiola has today undergone a routine operation on a back problem.
"The Manchester City boss has been suffering with severe back pain for some time lately, and flew out to Barcelona for emergency surgery performed by Dr Mireia Illueca. The surgery was a success, and Pep will now recover and rehabilitate in Barcelona.
"In his absence, assistant manager Juanma Lillo will oversee coaching of the first team on the training field and will assume duties on the touchline until Pep's return. He is expected to return after the forthcoming international break.
"Everyone at Manchester City wishes Pep a speedy recovery, and look forward to seeing him back in Manchester soon."
Guardiola's return is pencilled in for the trip to West Ham United on Sept 16.
