Guardiola suffering from back problem

The Barcelona manager, Pep Guardiola, has been diagnosed with a spinal disc hernia after he was admitted to hospital suffering from acute lower back pain.

The 40-year-old looked in discomfort during his side's 1-0 win at Valencia on Wednesday and the club confirmed Guardiola would be treated in hospital with drugs and an epidural.

"Pep is not feeling great," his assistant, Tito Vilanova, said. "He is having a bad time and doesn't know where to put himself."
