Barcelona president Sandro Rosell has revealed that the club's coach Tito Vilanova will return to duty in January.

The 44-year-old is currently recovering from a recurrence of cancer in his saliva glands after undergoing surgery earlier this month.

"He'll be back within 15 or 20 days, but he must spend some days at the hospital and rest," Rosell told reporters in Dubai on Friday.

"He will mix work with his treatment. The most important thing is his health. Right now football comes second."

Vilanova replaced Pep Guardiola as the Barcelona coach at the end of last season.
